expand (cos(θ)-1)(sin(θ)-1)

expand

(cos (θ) - 1) (sin (θ) - 1)

cos (θ) sin (θ) - cos (θ) - sin (θ) + 1

Solution steps

(cos (θ) - 1) (sin (θ) - 1)

Apply FOIL method

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

= cos (θ) sin (θ) - cos (θ) - sin (θ) + 1

(1 - \frac{2}{x})^{3}

(- sin (t) e^{t} + cos (t) e^{t})^{2}

(3 x + 5) (x - 25)

(1 - x^{2}) (1 - x^{2})

(e - f k) (e^{2} - e f k + f k^{2})
