Hi. I need help with these questions (see image)
Please show workings.
Answer c and d.

see explanation

Step-by-step explanation:

Using the chain rule and the standard derivatives

Given

y = f(g(x)) , then

= f'(g(x)) × g'(x) ← chain rule

(tanx) = sec²x , (cotx) = - csc²x

(c)

y = tan = tan

= sec² × ( )

    = sec² ×

    = sec² ×

   =

(d)

y = cot(1 + x)

= - csc²(1 + x) × (1 + x)

   = - csc²(1 + x) × 1

   = - csc²(1 + x)
