Dear all,

      The program is as follows (The "mw" files are also attached). The integraion "evalf(Int(k*sin(x)*T1,x=0..Pi/2,y=-Pi/6..-Pi/6+afa))" can not be worked out in several hours, but if the upper limit of x is changed to 0.5 (for example), the integration can be worked out quickly. I have tried to change the program to math model, however, the question still exists. How to solve this problem?
