expand sin(4(t-pi))cos(2(t-pi))

expand

sin (4 (t - π)) cos (2 (t - π))

sin (4 t) cos (2 t)

Solution steps

sin (4 (t - π)) cos (2 (t - π))

Expand

4 (t - π) : 4 t - 4 π

= sin (4 t - 4 π) cos (2 (t - π))

Expand

2 (t - π) : 2 t - 2 π

= sin (4 t - 4 π) cos (2 t - 2 π)

Rewrite using trig identities

= sin (4 t) cos (2 t - 2 π)

Rewrite using trig identities

= sin (4 t) cos (2 t)

(\frac{( 2 - 2 i )}{2})^{2}

\frac{d}{d y} ((x) (x^{4} + y^{2}))

\frac{2}{9 ( 1 - 2 x )}

\frac{30 ( 3600 + x ^{2} )}{x ^{2}}

\frac{5}{( 2 x + 1 ) ^{2}}
