Is -30 degree the same as 330 degrees? I am confused.
I am working on the directions of vectors.For many purposes, the answer is yes: because the angles are coterminal, if all you care about is direction, you can call it either one.
Sometimes, you care about how far you have turned to get to a direction, and then you would consider them different.
What is the problem you are working on?
Measured from standard position, a vector at 330° is the same as a vector at -30°. They each point in the same direction because they're the same vector. It's the rotation that's different. Measured as 330°, the vector has rotated counter-clockwise, from standard position. Measured as -30°, the vector has rotated clockwise, from standard position.I am working on the directions of vectors.
