How to find the angle between an XYZ vector and the y-axis? Please help!
A vector is given as follows:
A = 2i - 2j - 3k
The angle between A and the y-axis is, in degrees, closest to?:
90
119
151
61
29
c = ab sin[tex]\theta[/tex] ?
I tried:
cos[tex]\theta[/tex] = (AdotB)/(A x B)
I tried to set a vector along the y-axis to use as B.
Isolating [tex]\theta[/tex] yielded 56.3 degrees, which is apparently incorrect.
