you need to evaluate
To do this you need to consider
where
only after finding this will you be able to get an exact value
This technique will not work in this instance.

Let us consider the equation
there are infinite solutions of this equation
in the domain , the solutions are
The above two equations are identical. Every value of that satisfies equation 1 satisfies equation 2. If is a solution of equation 1, the is a root of the second equation.Equation1:
Equation 2:
For above solutions of
the last three of the above six are just the repetition of the first three. So the roots of Equation 2 can be
Hence, we can say that are the three roots of equation 2.
Multipying equation 2 by
we get
roots are
