expand 2cos(2)(x-pi/3)-1

expand

2 cos (2) (x - \frac{π}{3}) - 1

2 cos (2) x - \frac{2 π}{3} cos (2) - 1

Solution steps

2 cos (2) (x - \frac{π}{3}) - 1

Expand

2 cos (2) (x - \frac{π}{3}) : 2 cos (2) x - \frac{2 π}{3} cos (2)

= 2 cos (2) x - \frac{2 π}{3} cos (2) - 1

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

(sin (5 x) - cos (5 x))^{5}

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

\frac{- a ( b - 2 a ) + 3 c ( - b - 2 a )}{a ( b - 2 a ) + 3 c ( b - 2 a )}

(e^{2 t} + e^{- t})^{2}
