Hi all, I need to solve these two nonlinear equations for unknowns b and u. I have used solve command and maple is evaluating for last 5 hours. Is there any faster way to solve these equations? Also, can I somehow check if maple is not stuck in an infinite loop? equation 1: 16*Pi^2*1.5)*10^6*sqrt(Pi/(2*b^3))*((1000/3*((2/3)*exp(b*(u-4300))+3/4))*(exp(b*(u-4300)))^(3/2)/(exp(b*(u-4300))+1)+500*sqrt(exp(b*(u-4300)))^ln(exp(-b*(u-4300))+1)) = 1, equation 2: -(8*Pi^2*1.5)*10^6*sqrt((1/2)*Pi)*((1000*((2/5)*(exp(b*(u-4300)))^(5/2)/(exp(-b*(u-4300))+1)+(1/4)*(exp(b*(u-4300)))^(5/2)/(exp(b*(u-4300))+1)+(5/2)*(exp(b*(u-4300)))^(3/2)*ln(exp(-b*(u-4300))+1)))/b^(5/2)+(4300000/3*(((2/3)*exp(b*(u-4300))+3/4)*(exp(b*(u-4300)))^(3/2)/(exp(b*(u-4300))+1)+(3/2)*sqrt(exp(b*(u-4300)))*ln(exp(-b*(u-4300))+1)))/b^(3/2)) = -1290 solve in u and b. Thank you Manjeet
