Trigonometry - Graphing vectors.  TOPIC_SOLVED

My book shows three vectors, v, w, and u, which are illustrated geometrically on a plane. Each of them has their own length (magnitude) and direction. The following operation is performed as an example: 2v + 3w --------------------------------------------------- Is graphing an accurate depiction of ...

Re: Trigonometry - Graphing vectors.  TOPIC_SOLVED

I'm not sure where the confusion is with my question. I asked whether the length has to be specific. I never asked anything about the angle or slope. I'll ask the question again: Does the new vector line 2v have to be measured specifically when graphing it, Or do I kind of just visualize and guess t...

Trig: equality of position vectors- confused with definition  TOPIC_SOLVED

My book states the following: Two position vectors v and w are equal if and only if the terminal point of v is the same as the terminal point of w. This leads to the following result: Theorem: Equality of Vectors Two vectors v and w are equal if and only if their corresponding components are equal. ...

vectors: finding the actual speed and direction of aircraft  TOPIC_SOLVED

My book states the following: A Boeing 737 aircraft maintains a constant airspeed of 500 miles per hour headed due south. The jet stream is 80 miles per hour in the northeasterly direction. Express the velocity v of the 737 relative to the air. Answer: The velocity of the 737 relative to the air is ...

Re: vectors: finding the actual speed and direction of aircr  TOPIC_SOLVED

I had someone give me the following source: http://en.wikipedia.org/wiki/Airspeed It didn't really help me much though. I see that it said that true airspeed is the speed of the plane relative to the atmosphere. However, if you pick a stationary point of space in the atmosphere, it would seem to be ...
