I’m 85% sure it’s the long line on the bottom if not then uhm I guess I’m wrong
I believe the answer would be variable, because it is unknown which is very common for variables.
Plus, the variable definition (loose) is an unknown factor that can change in a trial.
I hope this helps!

1) expand csc and cotx identity
(1/sinx)-sinx = (cosx/sinx)*(cosx)
2) get common denominator on the left side
(1-sin^2x)/(sinx)= (cos^2x)/sinx
3) using cos^2x+sin^2x=1 you finished
cos^2(x)/sinx= cos^2(x)/sinx
hope that helps<span />
