Re: Integral question. Unable to solve

Hi.

there are 2 problems:

the first is that you are trying to calculate tan^2 multiplied by(x)

this should look like

the second is that the tan function is discontinuous over the range that you have specified

you don't specify what the numbers a and b are, Mathcad default is the arguments to trig functions are in radians.

If you are wanting them to be in degrees then you can change the definitions for a and b to

and this allows the integral to converge.

Hope this helps
