in this function contain another function which contain integral but when i replace is just take some of the function and other function is not acceptable i want ask  there is any way for plotting the function when i substitute all other function, is work for csc,sec,cosh, and for other not work and  infinity sign appear likesome other  like t,sin,cos,tan,tanh,sinh, so on

i did seperating but but is seems is not correct what is mistake in here?

in here  for jacobieliptic i got two lambda[0] same as paper did but in second one is different and is true make my ode be zero, but is so different from paper

In here i replaced but i don't know why still the D[1](f)(x, y, 0, t) is remain in my function in equation eqt1, beside this my function contain imaginary part we can plot this or we have to remove that somehow?

eval.mw

in this method i don't know in most of short equation i try to find the parameter but is just evaluating and nothing come up i don't know my way is wrong or write but i think i am right  but parameter not coming out, beside this in this equation give  me a warning regarding the parameters which say number of solution is more than 100 and dint show me that , how i can find the solution better than this?
