Question: What other Methods exist in Maple to Solve this Integral?

Hi,

Have the following integral to solve in Maple (2020):

Cap_Unit_Length := int((epsilon_0*epsilon_r*d*sqrt(1+(T*Pi*S)^2))/(epsilon_r*S*theta*tan(theta/2)+2*t),theta=0..Pi);

As Maple cannot find a closed expression, it returns the original input.  Is there any other approach in Maple I can use to attack this expression?  BTW, this is the expression for the distributed capacitance in a twisted wire pair.
