[tex] \frac{ \pi }{3} - \frac{ \pi }{6} [/tex]
Find the LCD for 3 and 6 :
6 = 2 . 3
Find the LCD : 2 * 3 = 6
Adjust fractions based on the LCD :
[tex] \frac{ \pi 2}{6} - \frac{ \pi}{6} [/tex]
[tex]= \frac{2 \pi - \pi }{6} [/tex]
[tex]2 \pi - \pi = \pi [/tex]
Add similar elements :
[tex] 2\pi - \pi = \pi [/tex]
Refine:
[tex]= \frac{ \pi }{6} [/tex]
hope this helps!
