expand (3+sin(x))^2

expand

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

9 + 6 sin (x) + sin^{2} (x)

Solution steps

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

Apply Perfect Square Formula:

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

(3 + sin (x))^{2} = 3^{2} + 2 \cdot 3 sin (x) + sin^{2} (x)

= 3^{2} + 2 \cdot 3 sin (x) + sin^{2} (x)

Simplify

3^{2} + 2 \cdot 3 sin (x) + sin^{2} (x) : 9 + 6 sin (x) + sin^{2} (x)

= 9 + 6 sin (x) + sin^{2} (x)

(- 3 - 3 i)^{5}

x^{\frac{2}{5}} (y^{\frac{1}{2}} + 2 x^{\frac{6}{5}})

\frac{1}{( 1 + t ^{2} ) ( 1 + r ^{2} )}

2 (sin^{4} (θ) + cos^{4} (θ)) + 4 sin^{2} (θ) cos^{2} (θ)

(a + x) a - x
