Question

Differentiate the following:
y = sin2(cos kx)

Sum
Advertisements

Solution

y = sin2(cos kx)

y = f(g(x)

`("d"y)/("d"x)` = f'(g(x)) . g'(x)

`("d"y)/("d"x)` = 2 sin(cos kx) × cos(cos kx) × – sin kx × k × 1

`("d"y)/("d"x)` = sin(2 cos kx) × – k sin kx

`("d"y)/("d"x)` = – k sin kx . sin(2 cos kx)
