expand (3+cos(θ))^30.3

expand

(3 + cos (θ))^{3} 0.3

8.1 + 8.1 cos (θ) + 2.7 cos^{2} (θ) + 0.3 cos^{3} (θ)

Solution steps

(3 + cos (θ))^{3} \cdot 0.3

= 0.3 (3 + cos (θ))^{3}

Expand

(3 + cos (θ))^{3} : 27 + 27 cos (θ) + 9 cos^{2} (θ) + cos^{3} (θ)

= 0.3 (27 + 27 cos (θ) + 9 cos^{2} (θ) + cos^{3} (θ))

Distribute parentheses

= 0.3 \cdot 27 + 0.3 \cdot 27 cos (θ) + 0.3 \cdot 9 cos^{2} (θ) + 0.3 cos^{3} (θ)

Simplify

0.3 \cdot 27 + 0.3 \cdot 27 cos (θ) + 0.3 \cdot 9 cos^{2} (θ) + 0.3 cos^{3} (θ) : 8.1 + 8.1 cos (θ) + 2.7 cos^{2} (θ) + 0.3 cos^{3} (θ)

= 8.1 + 8.1 cos (θ) + 2.7 cos^{2} (θ) + 0.3 cos^{3} (θ)

\frac{( x + 3 ) ( x - 8 )}{x}

\frac{1}{2} (arcsin (x) - \frac{1}{2} sin (2 arcsin (x))) + C

(x^{\frac{1}{4}} + y^{\frac{1}{4}}) (x^{\frac{1}{4}} - y^{\frac{1}{4}})
