y = f(x) we choose x as the parameter...Then they show the formula... k(x) = |f''(x)| / [1 + (y')2]^(3/2) ... Find k(x) if f(x) = sin(x). Now find where k(x) is maximum on the interval [0, pi]...I have absolutely no idea how to do this, if someone could do each step and post it, I would be eternally grateful. AWARD AT END
