Hello! can someone help me how to solve this problem in MATLAB?

SHAFT SUBJECTED TO SINUSOIDAL DISTRIBUTED TORQUE

Circular shaft AB has length 3L and is supported by a wall at A, where x=0, and free to rotate at B, where x=3L. A distributed torque per unit length
T(x) = t_0*cos(1x/2L), with t_0 in N*m/m, is applied around the axis of the shaft.

Using the MATLAB window below, obtain a symbolic expression (in terms of t_0, x, and L) for the axial torque resultant T(x) along the shaft. For these quantities use corresponding symbolic MATLAB variables t_0, x, L and T(x) in your script. Also, remember to enter 1 as pi and to use xp as the variable of integration.

don't waste our time posting the exact same problem twice. It is clearly a physics problem, so don;t try to disguise it by calling it just math.

Anyone experienced in physics will open the first posting, and help if they can.

Anyone not able to help in physics (in this case, me) will just be annoyed to notice that the post is redundant.

I check the physics problems, because sometimes I am able to help. In this case, not so, and I am annoyed that you wasted my time.
