Answer -
The equation of the given parabola is┬аy2┬а=4ax.
On differentiating┬аy2┬а=4ax┬аwith respect to┬аx, we have:

тИ┤The slope of the tangent at
is┬а
Then, the equation of thetangent at
is given by,
y┬атИТ 2at┬а=

Now, the slope of thenormal at
is given by,

Thus, the equation of the normal at (at2, 2at)is given as:
