Plotting a function defined by an integral on HP50

[cdecastro]

I entered all the integrals using the equation writer so the 50g produced the expressions I gave. I'll try entring them with 3 parameters.

Follow up...I tried entering y2(x) = s(1,x^2,2*t,t) into the graphing window (s is the integral sign) using equation writer as previously stated...still get the "bad argument" error when I attempt to plot it. Evaluation works fine.
