Normal line is perpendicular to tangent line at a given point x.
We can get the slope of normal from tangent equation i.e by taking negaive of inverse slope of tangent line.
For Example if slope of tangent = M then slope of normal = -1/M ,therefore with slope and value of x we can easily find eqaution of normal
Now, Let's jump in to have fun with, Practically trying them...
