# Find the Value of tan 1800°?

By signing up, you agree to our Terms of Service and Privacy Policy

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 ).

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.
