There is no answer.
Logically speaking, absolute value returns an output that is zero or positive.
Rearranging the equation gives:
|2x + 3| = -1
No matter what we substitute, we cannot get a negative number after applying the absolute value.
Therefore, the expression is undefined.
Answer:
a) cosθ = 
Step-by-step explanation:
<u><em> Step(i):</em></u>-
Given point ( x , y ) = ( - 2 , 3 )
We know that the polar co-ordinates
x = r cos θ and y = r sinθ
where

<u><em>Step(ii)</em></u>:-
x = r cos θ
cosθ 
cosθ = 
cosθ =
