WebQuestion 1: Evaluate the trig function tan (π / 6)? Solution: Given, tan (π / 6) Convert tan into sin and cosine, tan (π / 6) = sin (π / 6) / cos (π / 6) Take the values of sin (π / 6), cos (π / 6) from the trigonometric table. tan (π / 6) = (1/2) / (√3/2) tan (π / 6) = 1 / √3. Therefore the value of tan (π / 6) is 1 / √3.
