expand (v-xcos(y))^2

expand

(v - x cos (y))^{2}

v^{2} - 2 vx cos (y) + x^{2} cos^{2} (y)

Solution steps

(v - x cos (y))^{2}

Apply Perfect Square Formula:

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

(v - x cos (y))^{2} = v^{2} - 2 vx cos (y) + (x cos (y))^{2}

= v^{2} - 2 vx cos (y) + (x cos (y))^{2}

Simplify

(x cos (y))^{2} : x^{2} cos^{2} (y)

= v^{2} - 2 vx cos (y) + x^{2} cos^{2} (y)

(\frac{3 h + k - 3}{10})^{2}

1.43 (26 cos (32 i) - 26 sin (32 j))

\frac{2 s ^{2} - 6}{( s ^{2} - 4 ) ^{2}}

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