The Attempt at a Solution
I got up to the point where:
-[tex]\frac{3}{2}[/tex]y[tex]^{2}[/tex]=-7[tex]\sqrt{x^{2}+1}[/tex]+C
I solved for c=-143
but when I plug it back in, I get a mess of an equation in solving for y(x) and each time I plug it into check my answer, it comes up as wrong. Can anyone show me the mistake I am making? (My answer ends up being (-2/3(-7(x^2+1)^(1/2)-143))^(1/2) or some variation of that).
Thanks!
