expand cos(x)(cos(x)-sec(x))

expand

cos (x) (cos (x) - sec (x))

- sin^{2} (x)

Solution steps

cos (x) (cos (x) - sec (x))

Apply the distributive law:

a (b - c) = ab - a c

cos (x) (cos (x) - sec (x)) = cos (x) cos (x) - cos (x) sec (x)

= cos (x) cos (x) - cos (x) sec (x)

Simplify

cos (x) cos (x) - cos (x) sec (x) : - sin^{2} (x)

= - sin^{2} (x)

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

- 5 r^{2} sin (θ) (r^{2} - 9)

\frac{3}{n ( n + 3 )}

(4 a - b) (3 a + 2 b)

\frac{2 x + 1}{x ( x + 1 )}
