1. The problem statement, all variables and given/known data Find the lines that are (a) tangent and (b) normal to the curve y=x3 at the point (1,1). 2. Relevant equations 3. The attempt at a solution So first I found the derivative, 3x2. Then I used x=1 to find the slope which is 3. (a)y-1=3(x-1) y=3x-2 (b)y-1=(-1/3)(x-1) y=(-1/3)x+(4/3) Not really sure if I found the slope correctly tho..
