@kyelsoundproductions: as I'm using the angle with respect to the negative x (to go left) and negative y (to go down) axes (in quadrant 3), I'm using the supplement of 105 (the other half of the 180 degree straight line).

Technically, you can use -105 degrees (as it is clockwise from 0), and it should give you the same answer, but I like to stick to simple right angle trig and pay attention to the directions!

It is software purchased from TI, called "TI-Smartview". It's quite convenient, and can even be used on a smartboard, and with simultaneous equation, table, and graphical editors...

Thanks andieje! Slip of the tongue, I should have listened to it again... you are correct, sine should be opposite over hypotenuse, so the calculations are correct, my wording at that point is incorrect.

@MrdubsSAS on the second vector which 13n, why did you use 75 degrees for computation instead of 105 degrees?

Nice

thank you for this video! You're getting me through physics. You're 100 times better at explaining than my teacher.

Oh, and you should probably link the second video (part 2) in the description, just to be nice

This got me through college physics, the algebra based one obviously, but it was a great refresher before each quiz or test. Thanks @MrBdubsSAS

Thanks!

Wow, I learned more in these two videos that are about 15 minutes long total, than I had in an hour long lecture of physics from my teacher. Thank you a thousand times over, good sir, for showing this process. :)
