Formula's we're going to use:

(1) Cos(x + y) = Cos(x)Cos(y)-Sin(x)Sin(y)
(2) Cos(x)/Sin(x) = Cot(x)
(3) Sin(x)/Cos(x) = Tan(x)

(4) x+y/wz = x/wz + y/wz
To simplify we do the following:


=/ by Formula 1
=AMP Parsing Error of [[(Cos(a)Cos(B))/(Cos(a)Sin(B))]]: Invalid expression '[(Cos(a)Cos(B))/(Cos(a)Sin(B))]': syntax error at /home/ichudov/project_locations/algebra.com/templates/Algebra/Expression.pm line 203. . - by formula 4
= - by canceling out common terms
= by Formula 2 and 3
