vectors and angle...

How can I find the angle that a vector makes with the X, Y, or Z axis?

Example: V=24i + 12j - 20k. What angle does this vector make with x, y, and z axis?
 
Physics news on Phys.org
How do you find the angle between two vectors in general?
 
Do i use inverse cosine?
 
Ox : (1,0,0)
Oy : (0,1,0)
Oz : (0,0,1)
V : (24,12,-20)
"Do i use inverse cosine?"
If you don't, you should use a calculator to help you find the angle, its faster. I do it all the time.
 
Thank you. I got it now.
