expand cot(4x)(sin(4x)+2sin(4x)cos(3x))

expand

cot (4 x) (sin (4 x) + 2 sin (4 x) cos (3 x))

cot (4 x) sin (4 x) + 2 cos (3 x) cot (4 x) sin (4 x)

Solution steps

cot (4 x) (sin (4 x) + 2 sin (4 x) cos (3 x))

Apply the distributive law:

a (b + c) = ab + a c

cot (4 x) (sin (4 x) + 2 sin (4 x) cos (3 x)) = cot (4 x) sin (4 x) + cot (4 x) \cdot 2 sin (4 x) cos (3 x)

= cot (4 x) sin (4 x) + cot (4 x) \cdot 2 sin (4 x) cos (3 x)

= cot (4 x) sin (4 x) + 2 cos (3 x) cot (4 x) sin (4 x)

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

\frac{x + 69}{( x - 8 ) ( x + 3 )}

(6 - 2 x)^{2}

(cot (x) + tan (x))^{2}

\frac{( 1 - i ) ^{15}}{128}
