Physics Vectors Basic Mathematics MCQ (Single Correct)

p = (1 + cosec q) cos q, find

A

sin q – cosec 2 q

B

– sin q – cosec 2 q

C

– sin q – cos 2 q

D

sec q – cosec 2 q

Text Solution

Verified by Experts

The correct answer is:

P = (1 + cosec q) cosq

= cos q + cosec q . cosq

P = cosq + cot q

= – sin q – cosec 2 q
