expand (csc(θ)-1)(sin(θ)+1)

expand

(csc (θ) - 1) (sin (θ) + 1)

cos (θ) cot (θ)

Solution steps

(csc (θ) - 1) (sin (θ) + 1)

Apply FOIL method

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

= cos (θ) cot (θ)

(D - 3) (e^{3 x} y)

(x - 33)^{2}

(- 1 + 4 i) \cdot [2 (2, 3) - 3 (2, - 5)]

(x - 3)^{4}

(1 + \frac{x}{2})^{14}
