expand 2cos(2)(θ-pi/4)+1

expand

2 cos (2) (θ - \frac{π}{4}) + 1

2 cos (2) θ - \frac{π}{2} cos (2) + 1

Solution steps

2 cos (2) (θ - \frac{π}{4}) + 1

Expand

2 cos (2) (θ - \frac{π}{4}) : 2 cos (2) θ - \frac{π}{2} cos (2)

= 2 cos (2) θ - \frac{π}{2} cos (2) + 1

e^{x} \cdot (e^{x} + x e^{x})

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

- \frac{13}{( 2 x - 3 ) ^{2}}

\frac{3 x + 1}{( x - 1 ) ( x - 5 )}

x (- e^{- x + 4} + 1 = 0.9)
