Slope and equation of tangent line
The derivative of a function is interpreted as the slope of the tangent line to the curve of the function at a certain given point. In this section, we will explore the meaning of a derivative of a function, as well as learning how to find the slopepoint form of the equation of a tangent line, as well as normal lines, to a curve at multiple given points.
