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

see explanation

Step-by-step explanation:

Using the chain rule along with standard derivatives

Given

y = f(g(x)) , then

= f'(g(x)) × g'(x)

(sinx) = cosx , (cosx) = - sinx

(a)

y = sin x²

= cos x² × (x² )

   = cos x² × 2x

   = 2xcosx²

(b)

y = cos4x³

= - sin4x³ × (4x³ )

   = - sin4x³ × 12x²

   = - 12x²sin4x³

its a straight line parallel to the time axis

35 is an outlier
