Find L4 for f(x)=49cos(pi/2) from [2pi/4,2pi/2] I thought it would just be zero since there aren't any x's in f(x)? Apparently that's incorrect though. Any help would be wonderful!

Any help would be wonderful! Either you have a typo or you book has one becuase for all values of x. so the left endpoint sum would be since f(x)=0 for all values of x.
