point on curve ...

point not on curve

slope between points ...

for both x-values

note that two tangent lines exist with the desired properties.

finish up by finding the tangent line equations - February 19th 2009, 08:22 PMSaibot
Actually i did it this way and i got something totally different. What am i doing wrong?

What am i doing wrong?

i was following these instructions...:
