Q: What is the derivative of tangent?

The derivative of tangent is secant squared.

Q: How can we find the derivative of tangent of e to the x over x plus 1?

We can find the derivative by first applying the product rule and then simplifying the expression step by step.

Q: What is the derivative of e to the x?

The derivative of e to the x is just e to the x.

Q: How do we apply the quotient rule in finding the derivative of tangent of e to the x over x plus 1?

To apply the quotient rule, we square the denominator, multiply it with the derivative of the numerator, and subtract the numerator multiplied by the derivative of the denominator.
