Hi guys, this is my first post and i hope this is the correct thread to post in. I believe it is.
Find the resultant of the vectors
- 417∠11°
- 317∠87°
- 230∠154°
- 301∠304°
Give the angle between 0° and 360°.
Given that the OP is using degrees, no reference to the axis the angle is made from, and posted this in the Pre-Calc Forum I'm betting pretty heavily that the OP is either taking a Physics class (or perhaps an Engineering class) and practically every Intro Physics text does something like this to the notation.
So from that standpoint all angles are measured from the +x axis.
@kpae22 : The first vector has a magnitude of 417 (in whatever units) at an 11 degree angle to the +x axis. This means that the rectangular components are
$\displaystyle v_x = 417 ~ cos(11) \approx 409.339$
$\displaystyle v_y = 417 ~ sin(11) \approx 79.567$
Do this with the other three vectors and then add the components.
