Rather than memorizing three more formulas, if the integrand is negative, simply factor out −1 and evaluate the integral using one of the formulas already provided. To close this section, we examine one more formula: the integral resulting in the inverse tangent function. Example: Finding an...
Therefore, we don't have specific formulas for finding areas like this as we would if the shapes were defined as triangles or rectangles. This is where using integrals can be very helpful. Once the integral function is determined, it is used to find the area above or below the original ...

By inverse trig derivative formulas, d/dx(tan-1x) = 1/(1+x²) By product rule, d/dx(x tan-1x) = x d/dx(tan-1x) + tan-1x d/dx(x) = x/(1+x²) + tan-1x Answer: The derivative of x tan-1x is x/(1+x²) + tan-1x. Practice Questions on Inverse Trig Deriv...
