Simplify the expression.
-2(csc^2θ- cot^2θ) - 1

The value of given expression is - 3    

Step-by-step explanation:

Given expression as :

- 2 (cosec²Ф - cot²Ф ) - 1

Now , ∴ cosec²Ф = 1 + cot²Ф

SO, -2 (1 + cot²Ф - cot²Ф) - 1

Or,   -2 (1) - 1

Or, -2 - 1 = -3

Hence the value of given expression is - 3    Answer

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

i have no idea just need points sorry
