I am doing so bad in math and have no idea wat to do someone please help
Start that one by working with the left hand side because it is more complicated.
$\displaystyle \sin{x}+\sin{x}\cot^2{x}=\csc{x}$
Factor out a sine
$\displaystyle \sin{x}(1+\cot^2{x})=\csc{x}$
But, we know that $\displaystyle 1+\cot^2{x}=\csc^2{x}$
So, now we get
$\displaystyle \sin{x}\csc^2{x}=\csc{x}$
But, we also know that [tex]\frac{1}{\csc^2{x}}=frac{1}{\sin^2{x}}[/mATH]
So, now we get
$\displaystyle \sin{x}\frac{1}{\sin^2{x}}=\csc{x}$
You should be able to take it from here.
