Solution

Let y = `log[sec (e^(x^2))]`
Differentiating w.r.t. x, we get
`"dy"/"dx" = "d"/"dx"log[sec (e^(x^2))]`

= `(1)/(sec (e^(x^2))). "d"/"dx"[sec (e^(x^2))]`

= `(1)/(sec (e^(x^2))).sec(e^(x^2))tan(e^(x^2))."d"/"dx"(e^(x^2))`

= `tan(e^(x^2)).e^(x^2)."d"/"dx"(x^2)`

= `tan(e^(x^2)).e^(x^2).2x`
= `2x.e^(x^2)tan(e^(x^2))`.
