expand cos(x)(1+cos(x))

expand

cos (x) (1 + cos (x))

cos (x) + cos^{2} (x)

Solution steps

cos (x) (1 + cos (x))

Apply the distributive law:

a (b + c) = ab + a c

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

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

Simplify

cos (x) \cdot 1 + cos (x) cos (x) : cos (x) + cos^{2} (x)

= cos (x) + cos^{2} (x)

(tan (x) + sec (x)) (1 - sin (x))

\frac{( x ^{4} )}{( x - 1 ) ^{3}}

(x^{2} + 1) d x

cos (2 t) μ (t - π)

(5 x + 2)^{2}
