Please check my work. Thank you.
Find the dot product of the following vectors. Find the angle between the vectors.
Dot product v x w=-12-10=-22
cos of angle = -22/sq. root of 13 x sq. root of 41=-0.9529
the angle = 17.64 degrees.
Please tell me where I made a mistake, because when I graph the vectors, the angle looks like it is about 100 degrees.
Thank you very much.
