My Calc teacher, well, he's cruel. Hard problem..
Given that , find all of the points on the curve where the tangent line has to be horizontal and vertical.
I first solved the derivative of the equation to get 6x ²-6x-1 / (2x-1)².
From there, do I solve where the numerator is 0 (horizontal) and where the denominator is 0 (vertical)?
Thank you. I seem stuck, as always...
