Cosine ratios are exactly the same idea of sine ratios or <a href="[[glossary.html|{"keyword":"Tangent (in Trigonometry)"}]]">tangent</a> ratios. The only difference between it and the other two trigonometric ratios is that it is the ratio of the adjacent side to the hypotenuse of a right triangle.

Use cosine ratio to calculate angles and side (Cos = \( \frac{a}{h}\) )
