Calculate tan(359)°

Since our angle is greater than 270 and less than or equal to 360 degrees, it is located in Quadrant IV

In the fourth quadrant, the values for cos are positive only.

359 is an obtuse angle since it is greater than 90°

tan(359) = -0.043

Since 359° is less than 90, we can express this in terms of a cofunction

tan(θ) = cot(90 - θ) = cot(90 - 359) = cot(-269)
