SOLUTION: find dy/dx x=9/t y=t-t^2 I got as far as: dx/dt=-9t^-2 and dy/dt=1-2t dy/dx:1-2t/-9t^-2 is incorrect thank you for your help.

Question 885296: find dy/dx
x=9/t
y=t-t^2
I got as far as: dx/dt=-9t^-2 and dy/dt=1-2t dy/dx:1-2t/-9t^-2 is incorrect
thank you for your help.

This method may be different than what is expected and maybe this is non-standard, but if you want dy/dx, maybe try to eliminate t?

----- equation in only x and y. FIND DERIVATIVE OF THIS? Find the derivative based on this equation.
