Find the Value of tan 1800°?

Answer 1

#tan1800^@=0#

As tangent ratio has a cycle of #180^@# and #tan0^@=0#, the tangent ratio of any multiple of #180^@# is always #0#, hence

#tan1800^@=0#

The value of $\tan(1800^\circ)$ is undefined because the tangent function has a period of 180°, meaning it repeats every 180°. Therefore, $\tan(1800^\circ)$ is equivalent to $\tan(180^\circ)$ , which is undefined because the tangent function has vertical asymptotes every 90 degrees, including at $180^\circ$ .

Answer from HIX Tutor

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
