I want to integrate my two variable function w.r.t one variable.
And i used vpaintegral() for that, But it is not showing expected output.
i gave my script below
Aog = (2/pi)*(D*theta_d+Q*theta_q);
Akg = (4*(Q-D)/(pi*i))*(-1)^((i+4)/2)*sin(i*theta_q);
Ginvi = Ginvi+Akg*cos(p*i*(phi-theta));
Ginv = vpa((Ginvi+Aog), 4)
ginv = vpaintegral(Ginv, phi, 0, 2*pi)
I want to see "ginv" but it is showing like above.
What to add for getting output??
