expand cos(x)(1+tan(2x))

expand

cos (x) (1 + tan (2 x))

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

Solution steps

cos (x) (1 + tan (2 x))

Apply the distributive law:

a (b + c) = ab + a c

cos (x) (1 + tan (2 x)) = cos (x) \cdot 1 + cos (x) tan (2 x)

= cos (x) \cdot 1 + cos (x) tan (2 x)

Apply rule:

a \cdot 1 = a

cos (x) \cdot 1 = cos (x)

= cos (x) + cos (x) tan (2 x)

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

(x + 3)^{4}

(x - \frac{2}{x})^{5}

(x - \frac{2}{x})^{3}

(x^{\frac{2}{3}} - y^{\frac{1}{3}})^{3}
