Wait how did u find the initial sin and cosign angles for the magnitude equations. I understood how u got it for the first one, but you did the second one completely different

i don't get how you got the r what is the process for adding B & C together? this is my first time taking physics so im tying to understand

@yahyaanugod2103 2 жыл бұрын

The idea is just adding together the x-component of B with x-component of C and y-component of B with y-component of C. In this case add the 30 and -3.5(which are the x components of B and C) to get the x-component of R. Then add 0 and 6.06 to get the y-component of R. is then the x and y components of the resultant

In example 2, isn't the bearing angle the clockwise angle made from the north? So with the reference angle in this case 24.4 degree, the bearing should be 90-24.4=65.6 degree?

I’m confused, when do we use soh cah toa?

@DietEwok 5 жыл бұрын

Amp, you only use “SOH CAH TOA” as a reminder of what trigonometric functions to use when solving a right triangle. In this case the video shows a problem involving the box and we are given the angle 21 degrees and the hypotenuse. We are trying to find the opposite side, so with “SOH CAH TOA” you can use Sine of Cos since they both have “H” or the hypotenuse in their functions. Yet, we use Sin specifically because with algebraic manipulation we can find the opposite side.

Why is the angle of plane is 30 degrees? Isn't it 90? Thanks :)

@DietEwok 5 жыл бұрын

When using Vector components we always use the angle in reference to the positive X-axis or “polar axis” since it was N60E we just figured out the remaining space and use that as our vector. Same with S45E we have subtracted 360 from it to find 315

in the first question why aren't there any negative components all the work is in the second quadrent so the x components should be negative or is this différents someone pls explain.

Why did you subtract from 180 to find direction instead if 90?

@md-engineering 5 жыл бұрын

Mercy Fatolu she's looking for the reference angle from the X axis, 90 degrees would give you the reference angle from the y-axis.

Why direction angle is 120 ?

@MathWithMsRuddy 5 жыл бұрын

Great question! N30W means you start at due north (which would be 90 degrees for us) and head 30 degrees west (or left) from there, which would lead us into quadrant II. 90 + 30 = 120. This way of describing bearing is more for navigational purposes, so it may be a bit confusing when you see it the first time... Hope that makes sense! Let me know if you have other questions!
