Show all analysis? f(x) = 1/(sqrt(x-x^2)) I got this wrong on a calculus test and I can't figure out what I did wrong..

what rate is the angle between the? string and the horiztonal decreasing when 200 ft of string has been let out? [Calculus] Please help me understand step-by-step!

f(x) = 2x^2 + 3x^2 + 7x + 4, a = 4 f(x) = x^3 + 3 sin x + 2 cos x, a = 2 f(x) = 3 + x^2 + tan(xpi/2), x = (-1, 1), a = 3 f(x) = sqrt(x^3 + x^2 + x + 1), a = 2 Help with one or all please
