Trigonometric chart of cos30 and cos 60 deg

Trigonometric chart of sin 0 cos 0 sin 30 tan 0 cos30 and cos 60 deg


To remember the values of above table you can as follows:

(i) divide the numbers 0, 1, 2, 3 and 4 by 4,

(ii) take the positive square roots of all above numbers,

(iii) All above numbers will give us the values of sin 0°, sin 30°, sin 45°, sin 60° and sin 90° respectively.
