Has anyone ever experienced the following errors when attempting to integrate a function handle with respect to a certain variable? I followed the commands used to calculate an integral, and found myself with the following problems. Any advice would be greatly appreciated!

Yes, that means that the function you call integral with is called with an array of values - therefore your function (the long expression) should manage that. The way you've written it you will, implicitly, call it with arrays for t - so you'll have to replace ^ (which is the matrix-power in matlab) to .^ (which is the elementwise power), and where you have t*cos(t) (or the like) you'll also have to change from matrix-multiplication (*) to element-wise multiplication (.*).
