Given the function f (x) = 3x^4 – 6x^3 + 3x^2 . Find (if any) (i) the relative maximum and relative minimum (ii) the interval(s) where f(x) is increasing and decreasing. (iii) the interval(s) where f(x) is concave up and concave down

Find dy, dx i) x2y – y2x = e2x – 3 ii) y = tan x x iii) y = - k cos (x + h)2 x iv) y2 = x2 + sin xy
