Best ResponseYou've already chosen the best response.0\[\sin^2x+\cos^2x=1,\frac{ \sin^2 x}{ \sin^2x }+\frac{ \cos^2x }{ \sin^2x }=\frac{ 1 }{ \sin^2x }, 1+\cot^2x=cosec^2x\]

Best ResponseYou've already chosen the best response.0pvs: it appears you are in over your head. If you have a question such as this, and can't pick up on the idea of a trig identity you might want to slow down and back up.

Best ResponseYou've already chosen the best response.0$$ \tt \bf \Large(\csc x + 1)(\csc x 1)\\ \Large=\csc^2x\csc x +\csc x 1\\ \Large=\csc^2x1\\\\ \Large=\left(\dfrac{1}{\sin x}\right)^21\\ \Large=\dfrac{1}{\sin^2x}1\\ \Large=\dfrac{1}{\sin^2x}\dfrac{\sin^2x}{\sin^2x}\\\\ \Large=\dfrac{1\sin^2x}{\cos^2x}\\\\ \Large=\dfrac{\cos^2x}{\sin^2x}\\\\ \Large=\cot^2x $$ Please let me kow if you have any questions. Good luck.
