TRIGONOMETRIA 🚨 TANGENTE NA CIRCUNFERÊNCIA TRIGONOMÉTRICA #12

To obtain the tangent of an arc, we must draw a third axis that is tangent to point A. By joining the end of the arc AX (point X) to the center O and extending the radius of the circle, it will intersect the tangent axis. Why isn't there a tangent of 90 and 270? We know that division by zero doesn't exist. Therefore, we can conclude that a tangent of 90° doesn't exist. This is because the tangent function has its domain defined as follows: {x ∈ IR/ x ≠ π/2 + kπ, k ∈ Z}. In other words, when x = 90, 270, 450, 630... the tangent doesn't exist. What is the tangent of 120°? The tangent of 120° is equal to -√3. The tangent is equal to the ratio of sine to cosine. Therefore, we have tan(120) = sen(120)/cos(120). Note that 120 = 60 + 60.
