expand (cos(β)-1)(sin(β)-1)

expand

(cos (β) - 1) (sin (β) - 1)

cos (β) sin (β) - cos (β) - sin (β) + 1

Solution steps

(cos (β) - 1) (sin (β) - 1)

Apply FOIL method

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

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

(s + 170) (s^{2} - 2025) (s + 20 π)

(2 + cos (2 θ))^{2}

(3 x + \frac{\frac{5}{6}}{x})^{8}

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

(f \circ g) 2 (- 2 x + 1)^{2} - 5 (- 2 x + 1)
