expand cos(a)(sec(a)-cos(a)=sin^2(a))

Solution

expand

cos (a) (sec (a) - cos (a) = sin^{2} (a))

Solution

cos (a) sec (a) - cos^{2} (a) = sin^{2} (a)

Solution steps

cos (a) (sec (a) - cos (a) = sin^{2} (a))

= cos (a) (sec (a) - = cos (a) sin^{2} (a))

Apply the distributive law:

a (b - c) = ab - a c

a = cos (a), b = sec (a), c = cos (a) = sin^{2} (a)

cos (a) sec (a) - cos (a) cos (a) = sin^{2} (a)

Expand

cos (a) sec (a) - cos (a) cos (a) : cos (a) sec (a) - cos^{2} (a)

cos (a) sec (a) - cos^{2} (a) = sin^{2} (a)
