Hey everyone, I'm a new Calculus student, and this problem on derivatives is giving me lots of trouble. I can't get around it! Please help.(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

Find the coordinates of all points on the graph of y=1-x^2 at which the tangent line passes through the point (2,0).

2. Relevant equations

Possibly anything related to derivatives and slope, such as:

y-y1 = m(x-x1)

The power rule: nx^(n-1)

3. The attempt at a solution

All I know is the answer is: 2 (plus or minus) squareroot(3)

I took the derivative of the original equation in the hopes that I might see where I should be going, but I'm just stuck. I don't see where the point comes in. If someone could tell me the steps of how to get the answer so I could use that knowledge in the future, I'd really appreciate it!
