expand (tan(x)+tan(y))cos(x)cos(y)

expand

(tan (x) + tan (y)) cos (x) cos (y)

sin (x + y)

Solution steps

(tan (x) + tan (y)) cos (x) cos (y)

= cos (x) cos (y) (tan (x) + tan (y))

Apply the distributive law:

a (b + c) = ab + a c

cos (x) cos (y) (tan (x) + tan (y)) = cos (x) cos (y) tan (x) + cos (x) cos (y) tan (y)

= cos (x) cos (y) tan (x) + cos (x) cos (y) tan (y)

Simplify

cos (x) cos (y) tan (x) + cos (x) cos (y) tan (y) : sin (x + y)

= sin (x + y)

- \frac{2}{( 1 - r ) ^{2}}

(x) \cdot (x - 14)

(cos (x))^{4}

\frac{1}{( x - n ) ( x - na ) ( x - n a ^{2} )}
