Question

Find the exact value or type
"undefined"
tan(-315)
[?]

Answer 1

The tangent of -315 is opp/adj = 1/1 = 1

Explanation:

The angle -315 is in the 1st quadrant, in which we see a 45-45-90 triangle. Thus, this triangle has 'opposite side' = 1, 'adjacent side' = 1, and hypotenuse √2. The tangent of -315 is thus opp/adj = 1/1 = 1

Answer 2

the exact value of tan(-315) is 1
