Find the equation of the tangent and the normal to the following curves at the indicated points:
finding the slope of the tangent by differentiating the curve
m(tangent) at 
= 
normal is perpendicular to tangent so, m1m2 = – 1
m(normal) at 
= 
equation of tangent is given by y – y1 = m(tangent)(x – x1)
equation of normal is given by y – y1 = m(normal)(x – x1)
