Question

Differentiate the following:
y = cos (a3 + x3)

Sum
Advertisements

Solution

y = cos (a3 + x3)

[y = f(g(x)

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

`("d"y)/("d"x) = - sin ("a"^3 + x^3) "d"/("d"x) ("a"^3 + x^3)`

`("d"y)/("d"x)` = – sin (a3 + x3)(0 + 3x2)

`("d"y)/("d"x)` = – 3x2 sin (a3 + x3)
