expand (sec(θ)+tan(θ))(sin(θ)-1)

expand

(sec (θ) + tan (θ)) (sin (θ) - 1)

- cos (θ)

Solution steps

(sec (θ) + tan (θ)) (sin (θ) - 1)

Apply FOIL method

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

= - cos (θ)

8 x - 9 (4 - x = 23)

(2 i + 1)^{4}

(a_{0} x + a_{1} y)^{2} + p y

(1 - y)^{2}

2 x^{\frac{2}{3}} (x + 3)
