Find the equations of all lines having
slope 0 which are tangent to the curve
.
The
equation of the given curve is.
The slope of the tangent to the given curve at any point (x, y) is given by,
If the slope of the tangent is 0, then we have:
When x
= 1,
∴The
equation of the tangent through
is
given by,
Hence, the
equation of the required line is
