Tangent Line, Implicit Differentiation- Horizontal and Vertical Tangent line -Calculus

In this video I am gonna show you how we can find the points on a curve that tangent line to the curve is Horizontal or Vertical using implicit differentiation method.
Horizontal tangent line has slope equal zero.
For Vertical tangent line the slope is undefined.
In implicit differentiation, we differentiate each side of an equation with two variables (usually the variables are x and y) by treating one of the variables as a function of the other and usually y is a function of x (y=f(x)).
