How do you tell whether the value of tan 90 degrees is positive

Undefined We have: tan90^@ Know that, tantheta=(sintheta)/(costheta) So here, we get tan90^@=(sin90^@)/(cos90^@) Looking at the trigonometric table, we see that sin90^@=1,cos90^@=0. Therefore, tan90^@=1/0 Since anything divided by 0 (except 0 itself) is considered to be undefined, we get that tan90^@ is undefined as well.
