expand (cos(θ)+0.35)^2

expand

(cos (θ) + 0.35)^{2}

cos^{2} (θ) + 0.7 cos (θ) + 0.1225

Solution steps

(cos (θ) + 0.35)^{2}

Apply Perfect Square Formula:

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

(cos (θ) + 0.35)^{2} = cos^{2} (θ) + 2 cos (θ) \cdot 0.35 + 0.3 5^{2}

= cos^{2} (θ) + 2 cos (θ) \cdot 0.35 + 0.3 5^{2}

Simplify

cos^{2} (θ) + 2 cos (θ) \cdot 0.35 + 0.3 5^{2} : cos^{2} (θ) + 0.7 cos (θ) + 0.1225

= cos^{2} (θ) + 0.7 cos (θ) + 0.1225

\frac{3 x - 9}{( x ^{3} - 1 ) ( x - 2 ) ^{3} ( x ^{2} + x + 1 )}

\frac{2 x ( x - 3 )}{x ^{3} - x ^{2} - 6}

\frac{1}{( x + 5 ) ( x + 4 )}

(5 x + 8 y = 11, 5) (3 x + 5 y = 70)

\frac{s + 2}{( s + 1 ) ( s ^{2} + 4 )}
