Find the exact value of tan 15pi
To find the exact value of tan(15π), we can use the fact that the tangent function has a period of π.
Since 15π is equivalent to 5π, the tangent function has the same value at both 5π and 15π.
Therefore, the exact value of tan(15π) is the same as the exact value of tan(5π), which is 0.
So, tan(15π) = 0.
