Question

how to find the value of cos60 degree?

Answer 1

cos60degree = one upon two 1\2

Answer 2

Always remember cos60° has the same value as sin30°

To be precise:-----

value of sin (i.e.0°,30°,45°,60°,90°) is in reverse order in cos

(i.e. value of cos0°,30°,45°,60°,90° = Value of sin90°,60°,45°,30°,0°)

This is how you can find the value of cos60°.......There is no separate method or procedure for it....Just learn the sin values from the trigonometrical table given in your book....Rest all can be written from the value of sin
