Find the equations of the tangent line and normal line to the curve at the indicated point. Draw a sketch of the curve together with the tangent line and normal line.
18. y = 2x - x^3; (-2, 4)
20. y = - 8 / (sqrt(x)); (4, -4)
*****************
22. Find an equation of the tangent line to the curve y = 3x^2 - 4 that is parallel to the line 3x + y = 4.
24. Find an equation of each normal line to the curve y = x^3 - 3x that is parallel to the line 2x + 18y - 9 = 0.
*****************
Find the indicated derivative.
34. Dx ( 1 / (x+1) )
36. Dx ( sqrt(3x+5) )
56. y = ( 1 / cube root of x ) - x
*****************
60. Prove that there is no line through the point (1,2) that is tangent to the curve y = 4 - x^2.
