Question

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




​

Answer 1

Step-by-step 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.
