Question
Differentiate `sqrt(tansqrt(x))` w.r.t. x
Advertisements
Solution
Let y = `sqrt(tansqrt(x)`.
Using chain rule, we have
`("d"y)/("d"x) = 1/(2sqrt(tansqrt(x))) * "d"/("d"x) (tan sqrt(x))`
= `1/(2sqrt(tansqrt(x))) * sec^2 sqrt(x) "d"/("d"x) (sqrt(x))`
= `1/(2sqrt(tansqrt(x))) (sec^2 sqrt(x)) (1/(2sqrt(x)))`
= `(sec^2 sqrt(x))/(4sqrt(x) sqrt(tansqrt(x))`
