simplify (1-tan(x))(cos(2x))

simplify

(1 - tan (x)) (cos (2 x))

(1 - tan (x)) cos (2 x)

Solution steps

(1 - tan (x)) (cos (2 x))

Apply rule:

(a) = a

(cos (2 x)) = cos (2 x)

= (1 - tan (x)) cos (2 x)

(tan (2 x) + tan (x)) (cos (3 x) + cos (x))

\frac{3 x + 5}{( x + 1 ) ( x ^{2} + 3 x + 2 )}

(P + \frac{n ^{2} a}{v ^{2}}) (v - nb)

\frac{5}{( x + 4 ) ^{2}}

ln (\frac{( x ^{2} - 1 )}{x ^{2} + 1})

What is (1-tan(x))(cos(2x)) ?
The solution to (1-tan(x))(cos(2x)) is (1-tan(x))cos(2x)
