It's multiple uses of the chain rule:
\(\displaystyle \frac{d}{dx} [ (1 + sin^2(x) )^3 ] \)

\(\displaystyle = 3 (1 + sin^2(x) )^2 \cdot \frac{d}{dx} [ 1 + sin^2(x) ] \)

Can you finish from here?

FAQ: How Do You Differentiate (1+sin²x)³?

How do you differentiate (1+sin²x)³?

To differentiate (1+sin²x)³, you can use the chain rule and the power rule. First, you would multiply the exponent ³ to each term inside the parentheses, resulting in (1+sin²x)³. Then, you would use the chain rule to differentiate the term inside the parentheses, which would be 2sinx(cosx). Finally, you would use the power rule to differentiate the outer exponent, resulting in the final answer of 3(1+sin²x)²(2sinx)(cosx).
