Trigonometric Equations
- We are given the trigonometric equation
and we are supposed to solve it.
- We will be using the following identities.
- Let's proceed to solving the equation:
Now, when
, it means that x lies on the Y-axis, as an odd integral multiple of 
Hence, here we have:-
Here, we have and the answer is Option [A]..
Shortcut Method:-
- We can think smart by analyzing the options.
- Options [B], [C] and [D] have some integral multiples of
. At such values of angles, tan becomes 0.
• And cot is not even defined. So, Options [B], [C] and [D] cannot be correct. Hence, the Answer is Option [A].
