Factorise: tana(sina-cosa)+cota(cosa-sina)

Explanation:

tan(a) (sin(a) - cos(a) - cot(a) (sin(a) - cos(a)

(tan(a) - cot(a)(sin(a) - cos(a) )

(sin(a)/cos(a) - cos(a)/sin(a) ) (sin(a) - cos(a) )

(sin^2(a) - cos^2(a) )/[(sin(a)*cos(a)]  * (sin(a) - cos(a) )

(sin(a) - cos(a)) [sin(a) + cos(a) + 1] / (sin(a) * cos(a) )

That's as much as I can see that can be done.

basically anything for school but for getting t=into clubs or doing any legal things well it actually depends on what legal thing your doing but definitely not for drinking or going to the club or other things like that.
