expand r^2(sin^2(x)sin^2(y)+cos^2(x))

expand

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

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

Solution steps

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

Apply the distributive law:

a (b + c) = ab + a c

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

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

(a - b)^{12}

\frac{- x + 11}{3 x ( 4 x - 3 )}

(\frac{π}{4} + \frac{1}{2}) (x - 1)

(1 + 2 y)^{2}

(sin (x) - 1) (cos (x) - \frac{1}{2})
