# 14)Find the equations of the tangent and normal to the given curves at the indicated points: b)

We know that Slope of tangent at a point on given curve is given  by
Given equation of curve

at point (1,3)

Hence slope of tangent is 2
Now we know that,

Now, equation of tangent at point (1,3) with slope = 2 is
y = 2x + 1
y  -2x = 1
Similarly, equation of normal at point (1,3) with slope = -1/2 is
y = mx + c

equation of normal is
