Question 1.

Sin (x^{2} + 5)

Answer:

Question 2.

cos (sin x)

Answer:

Let y = cos (sin x)

\(\frac{\mathrm{d} y}{\mathrm{d} x}\) = – sin (sin x)x cos x – cos x sin (sin x)

Question 3.

sin (ax + b)

Answer:

Let y = sin (ax + b)

\(\frac{\mathrm{d} y}{\mathrm{d} x}\) = cos (ax + b)x a = a cos (ax + b)
