Find

A the slope of the curve

B the equation of the tangent

C. the equation of the normal

C the equation of the normal draw graph of the curve, tangent line, and normal line in the same square viewing window.

y= 1/(x-1) at x=2.

I have some understand of the slope of a curve. The more complicated formula, because I don't know where to find the simpler one (please help with that) below

[tex]m= (f(a+h)- f(a))/h

I understand that normal and tangent have opposite slopes. HEY MY MISSING GAME BOY!!! That's cool. It's been lost for 2 years.

Anyway, they have reciprocal slopes.

According the example for the tangent of a curve, plugging in 2 as 'a' and then I have trouble. Something like the whole top row gets put into the 'x' in the equation 1/(x-1). How does that work?

Thank yoU!
