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)

i can you answer this question sweetie!

step-by-step explanation:

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
