Hi
I have an equation: F=L*cos(theL). L is a constant. Integral of F over zero to (1/2)pi should give L. But I could not make that answer Please see below my code and help me how to fix this problem. I have much more complex equation but simplified my problem to this example.
syms L; theL=[0+0.001:pi/1000:pi/20.001] F=L*cos(theL); trapz(theL,F)
ans: (21828504695225120901251714223243*L)/162259276829213363391578010288128 + (634496096455597832693*pi*L)/2305843009213693952000
