<h2>What is Calculus 2?</h2>
<p>When it comes to learning Calculus 2, you&apos;ll need to come in with a solid understanding of the fundamentals of <a href='[[region_textbook.html|{"textbook_key":"calculus"}]]'>Calculus I</a> as you won&apos;t go far in this second course without knowing the ins-and-outs of limits, derivatives and applications of derivative. Our Calculus 2 course outline is organized logically with comprehensive notes each step of the way.</p>
<p>For this course, our certified StudyPug Calculus 2 tutors will guide you through six topics:</p>
<ul type="dash">
<li>Integrals</li>
<li>Integration Techniques</li>
<li>Integration Applications</li>
<li>Differential Equations</li>
<li>Sequence and Series</li>
<li>Parametric Equations and Polar Coordinates.</li>
</ul>

<h2>Is Calculus 2 Hard?</h2>
<p>Unless you are majoring in math, Calculus 2 will likely be the most difficult math course you will take thus far, mainly because it requires you to have a fair amount of maturity and creativity with math that you may not have needed up to this point. The hardship in understanding Calculus 2 isn&apos;t necessarily from committing the numerous formulas to memory, but instead, it can be difficult for knowing when to employ those Calculus 2 formulas. Sure, you&apos;re going to need to memorize all the fomulas, but you&apos;ll need to know the nuances of how the formulas operate, which in turn, helps you determine which Calculus 2 formula to use. It can be a dizzying amount of mental work that can be overwhelming for a student.</p>
<p>The perception of Calculus 2 being so difficult comes from the fact that a lot of students are actually surprisingly well prepared for Calculus 1 whereas this course often feels like a rude awakening. Compared to Calculus 1, it's relatively difficult to think of "real world application" that specifically depend on Calculus 2 concepts, and so there is a wide chasm between the material and students being able to relate to it. An easy Calculus 2 test can quickly turn into an impossible one when you start breaking down a nasty-looking integral that really only required a simple trig substitution.</p>
<p>Luckily, our Calculus 2 course is designed in a way where the complicated subject is broken into manageable chunks where we take time to walk you through those intricate nuances to bolster your grasp of the topic. If you&apos;re looking for Calculus 2 for dummies, we&apos;ve got a smart solution that will turn you into a Calculus 2 master in no time.</p>

<h2>What comes after Calculus 2?</h2>
<p>Firstly, it is highly recommended that you go through all of Calculus 1 before taking this Calculus 2. There&apos;s no real way around that as jumping into this course without a sound working knowledge of Calculus 1 is ill-advised. When anyone teaches Calculus 2, they will have to build on terms and formulas taught in Calculus 1. Besides that, another prerequisite for this course can be either <a href='[[region_textbook.html|{"textbook_key":"business-calculus"}]]'>Business Calculus</a> or <a href='[[region_textbook.html|{"textbook_key":"ap-calculus-ab"}]]'>AP Calculus AB</a> too.</p>
<p>After StudyPug has helped you conquer Calculus 2, your follow-up course should be either Calculus 3 or <a href='[[region_textbook.html|{"textbook_key":"linear-algebra"}]]'>Linear Algebra</a> where our instructors will further build on the knowledgebase you&apos;ve gained from taking this course.</p>

<h2>Who needs to take Calculus 2?</h2>
<p>In university, Calculus 2 is a required course for several academic disciplines including most science and math related majors like Physics, Engineering, Computer Science, etc. Basically, if you are in a field that uses math or science, you will absolutely encounter Calculus 2 in your course requirements.</p>
<p>Our Calculus 2 lessons are compatible with Calculus 2 textbooks such as  <a href="https://www.goodreads.com/book/show/61298.Calculus">Calculus: Early Transcendentals</a>; <a href="http://www.springer.com/us/book/9780387909752">Springer Calculus II</a>, <a href="https://www.pearson.com/us/higher-education/math---science/mathematics/calculus.html">Pearson Calculus</a>; and more.</p>

<h2>How to study for Calculus 2?</h2>
<p>In StudyPug, our education philosophy revolves around explaining complicated topics like Calculus 2 in an approachable manner. Instead of trying to parse truths from Googling out specific topics you may have a missed a class on, you can come here at any time to learn from our Calculus 2 tutorials to catch up. When searching for Calculus 2 topics, be specific so we can be precise in helping out with that burning Calculus 2 question that&apos;s been on your mind.</p>

<h2>Here are just some of the reasons why you&apos;ll want to get Calculus 2 help with StudyPug:</h2>
<ul type="dash">
<li>Our Calculus 2 tutorials are comprehensive, which means that we can answer any Calculus 2 questions that you may have. Whether it be Riemann Sum, Trig substitution, Alternating series test, Integral of trig functions, or P series test, StudyPug will provide answers you seek.</li>
<li>Our Calculus 2 practice is available immediately after each Calculus 2 lesson for you to practise the lessons&apos; material. After all, you can&apos;t master Calculus 2 without flexing that knowledge through practice.</li>

</ul>

<h2>What do you learn in Calculus 2?</h2>
<p>Calculus 2 is a bit of a mixed assortment of mathematical topics. The beginning of Calculus 2 deals with building on those aforementioned fundamentals of derivatives you should have touched on in Calculus 1.</p>
<p>You&apos;ll spend your early time formalizing antiderivatives, Riemann sums, the fundamental theorem, etc.</p>
<p>After that, you'll jump into integration techniques, which is usually the most difficult part of the course for most students. Here, you will pick up several different tricks to solve integration problems, but you&apos;ll also learn that integration is not as straightforward as differentiation.</p>
<p>From there, you'll then proceed to applications of integration to solve some very "fun" mathematical problems, like the area between two curves, volumes of different types of solids, average value of function, arc length, etc.</p>
<p>Next, you'll study differential equations where you will be exposed to an overview of the topic with its various solutions.</p>
<p>Following that, Sequence and Series is another heavy topic, but we divide it into 19 sub-topics so you can learn Calculus 2 at your own pace. Everything is covered here from an introduction to sequences to approximating functions with Taylor polynomials and error bounds.</p>
<p>Finally, we close out this course with a dive into Parametric Equations and Polar Coordinates. In this section, we teach you everything from how to define curves with parametric equations to understanding the arc length of polar curves.</p>
<p>If this sounds terrifying, fret not. StudyPug is committed to give you dedicated help with Calculus 2 questions by offering useful and easy-to-absorb Calculus 2 lessons.</p>

Intro

Intro to the root test for series convergence

Ex.1

Proving the limit of n to the power of 1/n equals 1

Ex.2

Applying the root test to (-3)^n / (2n)

Applying the root test to a series with n and pi exponents

Root test fails, using divergence test to show series diverges

Applying the root test to n^n over 3^n

In this section, we will look at a very useful limit question that will be used frequently when doing the root test. We will then learn and apply the root test to determine the convergence and divergence of series. Root test requires you to calculate the value of R using the formula below. If R is greater than 1, then the series is divergent. If R is less than 1, then the series is convergent. If R is equal to 1, then the test fails and you would have to use another test to show the convergence or divergence of the series. You may notice that this looks very similar to the ratio test. Also note that if the root test fails, then the ratio test will also fail. Thus, make sure to not waste time doing the ratio test if the root test fails.
