Given y^2 = tan x, what is dy/dx - Homework Help - eNotes.com
Given y^2 = tan x, what is dy/dx
It is given that `y^2 = tan x` . To determine `dy/dx` use implicit differentiation.
`y^2 = tan x`
`(d(y^2))/dx = (d(tan x))/dx`
=> `2*y*(dy/dx) = sec^2x`
=> `dy/dx = (sec^2x)/(2*y)`
=> `dy/dx = (sec^2x)/(2*sqrt(tan x))`

Okay, so to simplify the one that you just gave me, you're first going to distribute the 6x to both terms in the parentheses. So you end up with two answers which you'll stick back together to form
the final answer.
6x * 3x = 18x^2
6x * -x = -6x^2
Stick them back together:
