Questions & Answers

Q: How do you evaluate limits when direct substitution is not possible?

When direct substitution is not possible, you can try factoring the expression and canceling common factors, or you can use algebraic manipulations (such as multiplying by the conjugate) to simplify the expression and then evaluate the limit.

Q: What is the power rule for finding derivatives?

The power rule states that the derivative of a variable raised to a constant is equal to the constant multiplied by the variable raised to the constant minus one.

Q: How do you find the equation of a tangent line to a curve at a given point?

To find the equation of a tangent line, you need the slope of the tangent line, which is equal to the derivative of the function at that point. You also need the coordinates of the point. You can use the point-slope formula to write the equation of the tangent line.

Q: How can you use u-substitution to find antiderivatives?

To use u-substitution, you let u equal a certain expression within the function. Then, find the derivative of u with respect to x and rewrite the function in terms of u. Integrate the function with respect to u, and substitute back in the original variable at the end.
