simplify 3(sin(2x)cos(x)-sin^3(x))

simplify

3 (sin (2 x) cos (x) - sin^{3} (x))

3 cos (x) sin (2 x) - 3 sin^{3} (x)

Solution steps

3 (sin (2 x) cos (x) - sin^{3} (x))

Expand

3 (sin (2 x) cos (x) - sin^{3} (x)) : 3 cos (x) sin (2 x) - 3 sin^{3} (x)

= 3 cos (x) sin (2 x) - 3 sin^{3} (x)

3 (2 x - 1) d x

\frac{( 15 x + 8 y ) ^{2}}{400}

\frac{s ^{2} + 9 s + 8}{( s + 2 ) ( s ^{2} + 2 )}

\frac{( s ( s ^{2} - s + 1 ) )}{( s ^{2} + 1 ) ^{2}}

\frac{10 ( 63 - 4 21 )}{63}
