expand 0.8sin(0.628(x-2.4))

expand

0.8 \cdot sin (0.628 \cdot (x - 2.4))

0.8 (0.06355 \dots sin (0.628 x) - 0.99797 \dots cos (0.628 x))

Solution steps

0.8 sin (0.628 (x - 2.4))

Expand

0.628 (x - 2.4) : 0.628 x - 1.5072

= 0.8 sin (0.628 x - 1.5072)

Rewrite using trig identities

= 0.8 (0.06355 \dots sin (0.628 x) - 0.99797 \dots cos (0.628 x))

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

(\frac{1}{( 3 + h ) ^{2}}) - (\frac{1}{9})

\frac{( 2 sin ( 2 ) t )}{s ^{2} ( s ^{2} + 1 )}

\frac{d}{d x} ((f (x)) (12 x^{5} - 4 x + 3))

\frac{( 8 x ^{10} - 1 ) ^{8}}{65536 x ^{48}}
