Below are the few steps to memorize the trigonometry table. The trigonometric table is made up of the trigonometric ratios sine cosine tangent cosecant secant and cotangent which are all connected. Create a table with the top row listing the angles such as 0 30 45 60 90 and write all.

Now we can use the formula in below table to calculate the ratios from 120 to 360. Sin 2 r 1 cos 2 30. Some of the special trigonometric identities are given below Pythagorean Identities.

R p a2 b2 and argz tan 1 b a. When height and base side of the right triangle are known we can find out the sine cosine tangent secant cosecant and cotangent values using trigonometric formulas. Trigonometry Handbook Table of Contents Page Description Chapter 4.

All these are taken from a right angled triangle. Cos 2 r 1cos 2 31. Sin 2θ 2 sin θ cos θ.
