Question

Найти производную функции: y=(1+sin^2x)^4

Answer 1

$y'=((1+sin^2x)^4)'=4(1+sin^2x)^3*(1+sin^2x)'=4*(1+sin^2x)^3*\\*sin2x=4*(1+sin^2x)^3*2*sinx*cosx=8(1+sin^2)^3*sinx*cosx$

Answer 2

Y=(1+sin^2(2x))^4
y'  = 4(1+sin^2(2x))^3 * (1+sin^2(2x))' = 4(1+sin^2(2x))^3 * 2*sin(2x) * 2cos(2x) = 16sin(2x)cos(2x)*(1+sin^2(2x))^3
