Two tangent are drawn from the point `(-2,-1)` to parabola `y^2=4xdot` if `alpha` is the angle between these tangents, then find the value of `tanalphadot`

Explanation

To solve the problem of finding the value of \( \tan \alpha \) where \( \alpha \) is the angle between the two tangents drawn from the point \((-2, -1)\) to the parabola \( y^2 = 4x \), we can follow these steps:

### Step 1: Write the equation of the tangent to the parabola
The general equation of the tangent to the parabola \( y^2 = 4ax \) (where \( a = 1 \) for our parabola) is given by:
\[ y = mx + \frac{a}{m} \]
For our parabola \( y^2 = 4x \), the equation becomes:
