Graphical method to find magnitude and direction

[Infinitum]

Hi guys...
I am new to his website and i don't know if i am using the correct place to ask my question:shy:
Well the question is:
When a vector is given say A: a i^+b j^+ck^ then how to find the angle between the vector and x-axis: y- axis; z-axis
Thanq for ur time ...

Hi alex.hs! Start a new thread about your question. Make sure you include an attempt along with it!

For starters, to find angle from x axis, think about taking an unit vector along x-axis, and use the concept of dot-product.
