Angle of vector in component form
Find the vector's magnitude and direction. Use right as the +x direction and up as the +y direction.
[itex]\vec{A} = 3.50 \hat{i} - 7.70 \hat{j}[/itex]
Find [itex]\theta_A[/itex] degrees below the positive x-axis.
[itex]\theta_A = arctan\left ( \frac{7.70}{3.50} \right ) [/itex]
[itex]=65.55604522^\circ[/itex]
[itex]360^\circ - 65.55604522^\circ = 294.4439548^\circ[/itex]
But this is wrong. I also tried: -65[itex]^\circ[/itex] and 336[itex]^\circ[/itex]
