Question

If vector A⃗ has components Ax and Ay and makes an angle θ with the +x axis, then...

Answer 1

tanθ =Ax/Ay ?

Answer 2

Yup

Answer 3

isnt it supposed to be y/x instead?

Answer 4

wait crap. Yea. It's y/x.

Answer 5

A=Ax+Ay (where Ais the magnitude of A⃗ )
θ =AyAx
cosθ = AxA2x+A2y√
tanθ =AxAy
which of these is true? the first one?

Answer 6

Hmmm not quite sure...might want to look that up or ask someone else. I don't want to give any false info.

Answer 7

k cool thanks

Answer 8

yes the tangent of the angle is ay/ax

Answer 9

The vector is F = (Ax,Ay) and it has direction
@ such that tan@ = Ay/Ax
