(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Vectors A and B have scalar product -6.00 and their vector product has magnitude 4.00. What is the angle between these two vectors?

2. Relevant equations

A \dot B = ||A|| ||B|| cos θ and

A \cross B = ||A|| ||B|| sin θ

3. The attempt at a solution

Then I reasoned that tan(θ) = -4/6 so θ = cot(-4/6) = -33.69. I entered -33.7 and +33.7 degrees into Mastering Physics. Both are wrong. I know the answer should be in degrees. I'm confused about what I'm doing wrong. Thanks for helping out.
