expand (tan(θ)+1)(cos(θ)-1)

expand

(tan (θ) + 1) (cos (θ) - 1)

cos (θ) + sin (θ) - tan (θ) - 1

Solution steps

(tan (θ) + 1) (cos (θ) - 1)

Apply FOIL method

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

= cos (θ) + sin (θ) - tan (θ) - 1

(x) (x + 1)

6 (3 x + 5 y = 131)

sin (x) + cos (x) (x - 1)

(6 tan (θ) + 5)^{2}

π (1 - 2)
