Finding the derivative of y = ln ^ x (2x + 1)

Finding the derivative of y = ln ^ x (2x + 1)

Y = ln [x (2x + 1)] = ln (2x ^ 2 + x) so: y '= [1 / (2x ^ 2 + x)] * (2x ^ 2 + x)' = [1 / (2x ^ 2 + x)] * (4x + 1) = (4x + 1) / (2x ^ 2 + x). If y = LNX * (2x + 1), then: y = (1 / x) (2x + 1) + LNX * 2 = 2 + (1 / x) + 2lnx. = 2 (1 + LNX) + (1 / x)
