an =
Hi Gihahn,
To perform the integration, you need to use the int function from the Symbolic Math Toolbox and also ensure syms is used to define symbolic variables x, k, wo, and T.
Here's an example of how you can integrate your expression:
syms x k wo T
an = (1/T)*(int(3*cosd((k*wo*x)/T),0,0.01) + int(-3*cosd((k*wo*x)/T),0.01,0.02))
You can refer to the following MATLAB documentation for more information:
Best,
Umang
