Physics Vectors Basic Mathematics MCQ (Single Correct)

If y = sin(t2) , then will be -

A

2t cos(t2)

B

2 cos (t2) – 4t2 sin (t2)

C

4t2 sin (t2)

D

2 cos (t2)

Text Solution

Verified by Experts

The correct answer is:

y = sin(t2) ⇒ = 2 t cos (t2)

= cos t2 (2t) + 2t cos t2

= 2cost2 + 2t (-sint2) 2t

= 2 cos (t2) – 4t2 sin (t2)
