tan x = sin x/cos x. cosec x = 1/sin x. sec x = 1/cos x. cot x = 1/tan x. Given below are the steps to create and remember a trigonometric table. Step 1: Create a table with the top row listing the angles such as 0°, 30°, 45°, 60°, 90°, and write all trigonometric functions in the first column such as sin, cos, tan, cosec, sec, cot.

sin 0 = cos 90 sin 30 = cos 60 sin 45 = cos 45 sin60 = cos 30 sin 90 = cos 0 Hence, all the cos values can be filled now. We know that tan = (sin )/(cos ) Hence, all the tan values can be obtained from sin and cos values. tan 0 = sin 0 / cos 0 = 0/1 = 0. tan 30 = sin 30 / cos 30 tan 45 = sin 45 / cos 45 tan 60 = sin 60 / cos 60 tan 90 = sin 90 / cos 90 Start studying Sin cos tan 0, 30, 45, 60, 90.
