expand (-asin(w)-bsin(2*w))^2

expand

(- a \cdot sin (w) - b \cdot sin (2 \cdot w))^{2}

a^{2} sin^{2} (w) + 2 ab sin (w) sin (2 w) + b^{2} sin^{2} (2 w)

Solution steps

(- a sin (w) - b sin (2 w))^{2}

Apply Perfect Square Formula:

(a - b)^{2} = a^{2} - 2 ab + b^{2}

(- a sin (w) - b sin (2 w))^{2} = (- a sin (w))^{2} - 2 (- a sin (w)) b sin (2 w) + (b sin (2 w))^{2}

= (- a sin (w))^{2} - 2 (- a sin (w)) b sin (2 w) + (b sin (2 w))^{2}

Simplify

(- a sin (w))^{2} - 2 (- a sin (w)) b sin (2 w) + (b sin (2 w))^{2} : a^{2} sin^{2} (w) + 2 ab sin (w) sin (2 w) + b^{2} sin^{2} (2 w)

= a^{2} sin^{2} (w) + 2 ab sin (w) sin (2 w) + b^{2} sin^{2} (2 w)

(x + x x) \cdot 3 x^{6}

(2 e^{x} cos (2 x) + e^{x} sin (2 x))^{2}

- 11 (- \frac{12}{5} x + y = - 5)

\frac{2 x ^{2} + 4 x + 3}{( x + 1 ) ^{2} ( x ^{2} - 4 s + 13 )}

(4 a + 7 b = 1,) - (- 2 a + 7 b = - 5)
