What basic trigonometric identity would you use to verify that cot x sin x = cos x?

cot x = cos x / sin x.

Step-by-step explanation:

You would use cot x = cos x / sin x :

cot x sin x =  (cos x / sin x) * sin x

We cancel the sin x 's to give cos x.

you never say the total so we cant find the percentage used for petrol
