simplify 4(cos^2(2x)+sin^2(2y))

simplify

4 (cos^{2} (2 x) + sin^{2} (2 y))

4 cos^{2} (2 x) + 4 sin^{2} (2 y)

Solution steps

4 (cos^{2} (2 x) + sin^{2} (2 y))

Apply the distributive law:

a (b + c) = ab + a c

4 (cos^{2} (2 x) + sin^{2} (2 y)) = 4 cos^{2} (2 x) + 4 sin^{2} (2 y)

= 4 cos^{2} (2 x) + 4 sin^{2} (2 y)

(5 - 22) (5 + 2)

800 (2 x + 7 y = 121)

\frac{( x - 2 ) ^{2}}{2}

\frac{8}{( ( x ^{2} + 2 ) ( x ^{2} - 6 ) )}

(x^{2} - 1) (4 + x + 15)
