Analytical solution possible?
Posted:

A numerical solution is possible for the following ODE, but its analytical solution is sought. It goes on indefinitely without indication about inverse functions or messages.
Thanks in advance for any suggested workaround.
NoISQL = {SI'[t] == (R[t]  a)/(2 a  R[t])/R[t]^2,R'[t] == Cot[SI[t]]/R[t]}; DSolve[NoISQL, {SI, R}, t];
