expand (sin(x)+sin(y))^2

expand

(sin (x) + sin (y))^{2}

sin^{2} (x) + 2 sin (x) sin (y) + sin^{2} (y)

Solution steps

(sin (x) + sin (y))^{2}

Apply Perfect Square Formula:

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

(sin (x) + sin (y))^{2} = sin^{2} (x) + 2 sin (x) sin (y) + sin^{2} (y)

= sin^{2} (x) + 2 sin (x) sin (y) + sin^{2} (y)

x^{\frac{3}{2}} (x^{2} - 10 x + 17)

- \frac{12}{s ( s + 2 ) ( s + 3 )}

a (- 3, 5) b (- 3, - 7)

x (x - 3)

x (x - 2)
