Questions & Answers

Q: What is the power rule in calculus?

The power rule in calculus states that the derivative of a variable raised to a constant is equal to the constant multiplied by the variable raised to the power minus one. For example, the derivative of x^3 is 3x^2.

Q: How does the chain rule work in calculus?

The chain rule in calculus allows us to find the derivative of a composite function. It involves differentiating the outer function while keeping the inner part the same, and then multiplying by the derivative of the inner function. This process allows us to find the derivative of complex functions.

Q: What is the derivative of the natural logarithm function?

The derivative of the natural logarithm function ln(x) is equal to 1/x. This means that when differentiating ln(u), where u is a function of x, we need to use the chain rule and multiply by the derivative of u.

Q: How do you find the derivative of the inverse trigonometric functions?

The derivatives of inverse trigonometric functions can be found using specific formulas. For example, the derivative of the inverse sine function is equal to 1/sqrt(1 - u^2), where u is the function of x. The signs and constants differ for each inverse trigonometric function.

Summary & Key Takeaways
