expand (cos(v)-1)^2

expand

(cos (v) - 1)^{2}

cos^{2} (v) - 2 cos (v) + 1

Solution steps

(cos (v) - 1)^{2}

Apply Perfect Square Formula:

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

(cos (v) - 1)^{2} = cos^{2} (v) - 2 cos (v) \cdot 1 + 1^{2}

= cos^{2} (v) - 2 cos (v) \cdot 1 + 1^{2}

Simplify

cos^{2} (v) - 2 cos (v) \cdot 1 + 1^{2} : cos^{2} (v) - 2 cos (v) + 1

= cos^{2} (v) - 2 cos (v) + 1

(x^{2} - x + 3)^{3} f^{'} (2)

(2, - 2) y (4, 1)

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

K (1 + A + \frac{- A - 2 B}{z} + B + \frac{B}{z ^{2}})
