expand (a-acos(x))^2

expand

(a - a cos (x))^{2}

a^{2} - 2 a^{2} cos (x) + a^{2} cos^{2} (x)

Solution steps

(a - a cos (x))^{2}

Apply Perfect Square Formula:

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

(a - a cos (x))^{2} = a^{2} - 2 aa cos (x) + (a cos (x))^{2}

= a^{2} - 2 aa cos (x) + (a cos (x))^{2}

Simplify

a^{2} - 2 aa cos (x) + (a cos (x))^{2} : a^{2} - 2 a^{2} cos (x) + a^{2} cos^{2} (x)

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

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

(e^{x} sin (x) - e^{x} cos (x))^{2}

(2 - x + x + 4) (2 - x - x + 4)

2 x ln (3 x) + (9 x^{2} + 2)^{3}

\frac{1}{( n - 1 ) n}
