Q. What is the value of tan(3π) ?Choose 1 answer:(A) 21(B) 33(C) 23(D) 3
Recalling the unit circle: To find the value of tan(3π), we need to recall the unit circle or the special triangles. The angle 3π radians corresponds to 60 degrees.
Using a 30−60−90 triangle: In a 30−60−90 right triangle, the sides are in the ratio 1:3:2. The shortest side (opposite the 30-degree angle) is 1, the side opposite the 60-degree angle (which is tan(3π)) is 3, and the hypotenuse (opposite the 90-degree angle) is 2.
Finding the tangent of 3π: The tangent of an angle in a right triangle is the ratio of the length of the opposite side to the length of the adjacent side. So, tan(3π)=length of adjacent side to 60∘length of opposite side to 60∘.
Applying the side ratios: Using the side ratios for a 30−60−90 triangle, tan(3π)=13=3.
