If tan(t)= -(5/9) , evaluate tan (-t) and cot (-t).

Question

tan(-t) = ?

cot(-t) = ?

Answer 1

If tan(t)= -(5/9) , evaluate tan (-t) and cot (-t).

tan(-t) = ?

cot(-t) = ?

The Tangent is negative in the 2nd and 4th quadrant.

If tan(t) = -(5/9), then tan(-t) = 5/9 in the 1st or 3rd quadrant, and cot(-t) = 9/5 in 1st or 3rd quadrant.
