Differentiating (1+sin²x)³: A Step-by-Step Guide

In summary, to differentiate (1+sin²x)³, you can use the chain rule and the power rule. This allows us to find the derivative of the function, which is useful in various real-life situations. A step-by-step guide can be helpful in understanding and following the process. Other methods, such as the product rule or quotient rule, can also be used, but the chain rule and power rule are the most efficient for this function. The derivative represents the rate of change of a function, making it a fundamental concept in calculus with practical applications in physics, economics, and engineering.

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?

1. 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).

2. Why do we need to differentiate (1+sin²x)³?

Differentiating (1+sin²x)³ allows us to find the derivative of this function, which is useful in many areas of science such as physics, engineering, and economics.
