# Find the equation

finding the slope of the tangent by differentiating the curve

m(tangent) at (1, – 2) = 1

normal is perpendicular to tangent so, m1m2 = – 1

m(normal) at (1, – 2) = – 1

equation of tangent is given by y – y1 = m(tangent)(x – x1)

y + 2 = 1(x – 1)

y = x – 3

equation of normal is given by y – y1 = m(normal)(x – x1)

y + 2 = – 1(x – 1)

y + x + 1 = 0
