limit as x approaches 0+of tan(x)

x \to 0 + lim (tan (x))

0

Solution steps

x \to 0 + lim (tan (x))

Plug in the value

x = 0

= tan (0)

Use the following trivial identity:

tan (0) = 0

tan (x)

periodicity table with

πn

cycle:

x 0 \frac{π}{6} \frac{π}{4} \frac{π}{3} \frac{π}{2} \frac{2 π}{3} \frac{3 π}{4} \frac{5 π}{6} tan (x) 0 \frac{3}{3} 13 \pm \infty - 3 - 1 - \frac{3}{3}

= 0
