Aʙᴏᴜᴛ Tʜɪs Vɪᴅᴇᴏ – This video looks at a shortcut to resolve a velocity or a force into horizontal and vertical components or i and j vectors, using the Rec or Rectangular Coordinate feature. This is a method of finding both at the same time, but be careful where you use it. There may be circumstances where you must stick to using Sin and Cos of the angle.
