expand (cos(θ)-x)^2

expand

(cos (θ) - x)^{2}

cos^{2} (θ) - 2 x cos (θ) + x^{2}

Solution steps

(cos (θ) - x)^{2}

Apply Perfect Square Formula:

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

(cos (θ) - x)^{2} = cos^{2} (θ) - 2 cos (θ) x + x^{2}

= cos^{2} (θ) - 2 cos (θ) x + x^{2}

= cos^{2} (θ) - 2 x cos (θ) + x^{2}

e^{i (\frac{3 y \cdot a}{2} - \frac{2 π}{3})}

\frac{d}{d x} ((x + 1) ln (x)) - x + 1

\frac{4 e ^{x}}{( 4 + e ^{x} ) ^{2}}

(- 4 + \frac{6 i}{n})^{2}

(cos (3 t) - \frac{1}{3} cos^{3} (3 t)) cos (3 t)
