I'm trying to use the quad function to evaluate the integral of the magnitude of y'(x) where
y(x)= (-3cos(t), -2sin(t), t) from 0 to 2pi.

Code so far:
v = [-3*sin(t), -2*cos(t), 1];
j=norm(v)
F = @(t)norm(v)
ANS1 = quad(F,0,2*pi)

Error:
??? Index exceeds matrix dimensions.

Error in ==> quad at 85
if ~isfinite(y(7))

Thanks so much for any help!!!!
