Question

please solve it and give right answer​

Answer 1

3 sin (5-3t)

...............

Answer 2

Answer:

dy/dt=3sinp=3sin(5-3t)

Step-by-step explanation:

y=cos(5-3t)

Let p=5-3t

dp/dt=-3..............(1)

y = cos p

dy/dp=-sin p...............(2)

Thus dy/dt =dy/dp * dp/dt

=(-sin p) (-3)

dy/dt=3sinp=3sin(5-3t)
