Hey guys can you help me out with this:
Given the ellipse 4x^2 + 9y^2 = 36,
a) Find .
is this correct:
b) Give the equations of all tangent lines to the graph at x = 1.
at this point I plug in 1 in the original function to get y right?
I got this weird number for y when I did that:
are my calculations correct?
