simplify (2cos(x)-sqrt(2))(2sin(x)-sqrt(2))

simplify

(2 cos (x) - 2) (2 sin (x) - 2)

2 sin (2 x) - 22 cos (x) - 22 sin (x) + 2

Solution steps

(2 cos (x) - 2) (2 sin (x) - 2)

Apply FOIL method

(2 cos (x) - 2) (2 sin (x) - 2) : 2 sin (2 x) - 22 cos (x) - 22 sin (x) + 2

= 2 sin (2 x) - 22 cos (x) - 22 sin (x) + 2

\frac{x}{( x - 4 ) ( x + 2 )}

\frac{( x + 1 )}{x ( x - 0.5 )}

\frac{1}{x ( x - a + b )}

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

6 \cdot (\frac{3}{4} + \frac{x}{2})
