expand cos(x)\times (1+cos(x))

expand

cos (x) \cdot (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)

(1 + y) \cdot ln (1 + y) + (4 + y) \cdot ln (4 + y)

cos (x y) (y + x \frac{d y}{d x})

(y^{3} - 8) 1 + y^{4}

\frac{( s - 2 )}{( s + 4 ) ( s ^{2} + 9 )}

\frac{3}{2} (2 - \frac{x}{3})^{2} - \frac{x}{4} (2 - \frac{x}{3})^{2}
