factor cos^2(a)-cos^2(b)

factor

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

(cos (a) + cos (b)) (cos (a) - cos (b))

Solution steps

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

Apply Difference of Two Squares Formula:

x^{2} - y^{2} = (x + y) (x - y)

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

= (cos (a) + cos (b)) (cos (a) - cos (b))

(4 x^{2} + 5) (3 x^{2} + 2)

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

55 x^{2} - 3 x + 2582 x^{2} - 9 x^{261}

x^{2} + 121 x

(a^{- 2} \cdot b)^{\frac{1}{2}} \cdot (a \cdot b^{- 3})^{\frac{1}{3}}
