Find the length of the curve y=x^2-4|x|-x from x=-4 to x=4.
The Attempt at a Solution
I realized there is a corner at x=0 so i tried to get around this by pluggin in x for x>=0 and -x for x<0. However, my integrals don't match the answer.
Which does not match the answer 19.56, what did I do wrong?
Also, when I do try to find arc length in parametric curves and often more that not, a curve repeats itself in a given interval. How do I detect this and avoid it to just find length of one cycle?
