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

simplify

2 (sin (x) cos (x) - cos^{2} (x))

2 cos (x) sin (x) - 2 cos^{2} (x)

Solution steps

2 (sin (x) cos (x) - cos^{2} (x))

Expand

2 (sin (x) cos (x) - cos^{2} (x)) : 2 cos (x) sin (x) - 2 cos^{2} (x)

= 2 cos (x) sin (x) - 2 cos^{2} (x)

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

\frac{x + 2}{( x + 3 ) ( x - 4 )} + \frac{x - 1}{2 + 2 x}

6 x^{3} δ (x - 2)

(4 - x) ln (x + 7)

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