Required
The type of solution
A linear equation is represented as:
For the first equation:
For the second:
We have:
By comparison:
<em>Hence, the system has a unique solution.</em>
We have been given that . We are asked to prove that .
First of all, we will solve for tangent of alpha as:
Now, we will divide left side of our given equation by as:
We know that , so we will get:
Upon substituting , we will get:
Hence proved.
