उत्तर

Let sinx2 + sin2x + sin2(x2)

∴ `"dy"/"dx" = "d"/"dx" sin(x^2) + "d"/"dx" (sinx)^2 + "d"/"dx" (sin x^2)^2`

= `cos(x^2) "d"/"dx" (x^2) + 2 sinx * "d"/"dx" (sin x) + 2 sinx^2  "d"/"dx" (sin x^2)`

= `2x cosx^2  +  2 sin x cos x + 2sinx^2 cosx^2  "d"/"dx" x^2`

= `2x cosx^2  +  2 sin x cos x + 2 sin x^2 cos x^2 xx 2x`

= 2x cos(x2) + sin 2x + 2x sin 2(x2)
