expand cos(θ)(tan(θ)-sec(θ))

expand

cos (θ) (tan (θ) - sec (θ))

sin (θ) - 1

Solution steps

cos (θ) (tan (θ) - sec (θ))

Apply the distributive law:

a (b - c) = ab - a c

cos (θ) (tan (θ) - sec (θ)) = cos (θ) tan (θ) - cos (θ) sec (θ)

= cos (θ) tan (θ) - cos (θ) sec (θ)

Simplify

cos (θ) tan (θ) - cos (θ) sec (θ) : sin (θ) - 1

= sin (θ) - 1

(\times + 3) (x^{2} - 3 x + 9)

(y - x y^{2} + 2 y e^{x}) d x + (x - x^{2} y + 2 e^{x}) d y

(1 - i w)^{2}

a ln (\frac{am}{( a + b ) t}) + b ln (\frac{bm}{( a + b ) t})

\frac{( 8 ( a ^{2} - s ^{2} ) )}{( a ^{2} + s ^{2} ) ^{2}}
