expand sqrt((1-cos(θ))^2+sin^2(θ))

expand

(1 - cos (θ))^{2} + sin^{2} (θ)

2 - 2 cos (θ)

Solution steps

(1 - cos (θ))^{2} + sin^{2} (θ)

Expand

(1 - cos (θ))^{2} + sin^{2} (θ) : 1 - 2 cos (θ) + cos^{2} (θ) + sin^{2} (θ)

= 1 - 2 cos (θ) + cos^{2} (θ) + sin^{2} (θ)

Rewrite using trig identities

= 2 - 2 cos (θ)

(4 x - 1) ln (2)

\frac{( 1 - t ) b \cdot d}{b ( 1 - t ) + c}

\frac{1}{k ( a - x ) ( b - x )}

\frac{\partial}{\partial t} ((x) (2 s - t))

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