Going Off on a Tangent

Geometry Level 3

The value of tan ⁡ ( 89.9 ) \tan(89.9) lies in which of the following ranges?

To clarify, the angle is measured in radian, not degrees.

[ 1 , ∞ ) [1,\infty) [ 0 , 1 ) [0,1) [ − 1 , 0 ) [-1,0) ( − ∞ , − 1 ) (-\infty,-1)

Ohh. Got trolled again. The given angle is in radian. So 89.9 r a d = 515 0 ∘ ∈ ( π , 3 π 2 ) 89.9\,rad=5150^{\circ}\in\left(\pi,\displaystyle\frac{3\pi}{2}\right)
