Can a angle be negative
WebSep 13, 2024 · answer=-26.15 degrees. I was wondering why Snell's Law gave me a negative angle. My reasoning was because the angle fell below the x-axis, and can't think of anything else. You have 90 degrees going upwards, and -90 degrees going downwards. Is there more to it? Thank you. edit: theta = arcsin (1.333sin (80degrees)/1.0003) theta = … WebJul 24, 2024 · Angle measure can be positive or negative, depending on the direction of rotation. Positive angles (Figure a) result from counterclockwise rotation, and negative angles (Figure b) result from clockwise rotation. An angle with its initial side on the x‐axis is said to be in standard position. Can I have a negative cosine? .

In order to determine if the angle between two vectors is positive or not, there would have to be a reference normal plane vector (vn). If so, yes you can. There is a way to check if the angle between those two vectors should be negative. First take the cross product of the two vectors (v1 x v2) to get the normal of the plane (v3).
WebOct 27, 2011 · Two angles are complementary if they both add up to 90 degrees. This means that a complementary angle would have to be negative 23 degrees if the given … WebSo we rose negative 1. We actually went down. So our rise is negative 1 when our run-- when our change in x-- is 3. So change in y over change in x is negative 1 over 3, or we could say that our slope is negative 1/3. Let me scroll over a little bit. It is negative 1/3. And I want to show you that we can do this with any two points on the line.
