Solve, finding all the solutions in [O, 2pi).
cot(x) cos(x) + cot(x) = 0

Step-by-step explanation:

cot(x) cos(x) + cot(x) = 0

cot(x) (cos(x) + 1) = 0

cot(x) = 0 or cos(x) = -1

cot(x) = 0

x = π/2, 3π/2

x ≠ 0, π

cos(x) = -1

x = π

Therefore, the answer is x = π/2, 3π/2.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
