expand cot(x)(cos(2x)-1)

expand

cot (x) (cos (2 x) - 1)

cos (2 x) cot (x) - cot (x)

Solution steps

cot (x) (cos (2 x) - 1)

Apply the distributive law:

a (b - c) = ab - a c

cot (x) (cos (2 x) - 1) = cot (x) cos (2 x) - cot (x) \cdot 1

= cot (x) cos (2 x) - cot (x) \cdot 1

Simplify

cot (x) cos (2 x) - cot (x) \cdot 1 : cos (2 x) cot (x) - cot (x)

= cos (2 x) cot (x) - cot (x)

(i - 12) (i + 9)

tan (s) (cot (s) + csc (s))

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

\frac{x ^{4} + 3 x}{( x ^{2} - 4 ) ( x + 1 )}

x (x cos (x) + 2 sin (x))
