expand (cot(2x)+1)(sin(2x)-1)

expand

(cot (2 x) + 1) (sin (2 x) - 1)

cot (2 x) sin (2 x) - cot (2 x) + sin (2 x) - 1

Solution steps

(cot (2 x) + 1) (sin (2 x) - 1)

Apply FOIL method

(cot (2 x) + 1) (sin (2 x) - 1) : cot (2 x) sin (2 x) - cot (2 x) + sin (2 x) - 1

= cot (2 x) sin (2 x) - cot (2 x) + sin (2 x) - 1

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

\frac{10 ( x - 4 )}{3}

\frac{10 x - 6}{( x - 3 ) ^{4}}

(ab)^{2} + (b v)^{2} + (v a)^{2}

a^{k (k + 1)}
