Thank you! But how can I determine where the position of theta is going to be?

@HowToPhysics 3 жыл бұрын

Typically we put theta at the origin and use the positive x-axis as a reference for zero degrees.

Could you summarize the rule of why tan^-1 giving negative angles only work in the 1st and 4th quadrants

@HowToPhysics 2 жыл бұрын

Sure! When you put things in to the argument of inverse tan it is tan^-1(opposite/adjacent) ... most calculators have no way of knowing if you're trying to put tan^-1(+opp/+adj) or tan^-1(-opp/-adj) and the same with tan^-1(+opp/-adj) or tan^-1(-opp/+adj) ... so those calculators will only give you an answer between 0 and 180 degrees and expect you to take the extra step to decide if you need to add 180 degrees or not. Hope this helps, I know it's confusing to write out!

This helped me with my first problem, but how would we find the magnitude of vectors that dont become right angled triangles?

@HowToPhysics 2 жыл бұрын

If the two vectors don't make a right triangle you would use the component method: kzfaq.info/get/bejne/fbVyY7Netd-oY5s.html

hello, why is the angle theta always equal to the direction of the vector?

@HowToPhysics 2 жыл бұрын

If the vector is at an angle then we have to use theta and the unit circle. If the vector is just going WEST or EAST we can simply say that WEST or EAST is the direction and not worry about theta. Some physics teachers do not use theta and the unit circle, they instead use something called "bearings" for example, 30 degrees West of North. I don't have a video using bearings but it's pretty easy to find one. Hope this helped!

What happens if the magnitude and the angle are the given, but the x and y intercept are missing?

@HowToPhysics Жыл бұрын

Vectors don't have x and y intercepts, only magnitude and direction. You can, however, move a vector anywhere you want on an x vs y graph. This is often used for adding vectors. This video might be helpful: kzfaq.info/get/bejne/ldt3lZthp8nZpKc.html

Lol how did u get 4.24. Please help.

@HowToPhysics Жыл бұрын

Using the Pythagorean theorem you use 3 for each side (x and y) then solve for the hypotenuse. To do this you have to square each side then add them together (3^2 + 3^2 = 18). This is equal to the hypotenuse SQUARED so you have to take the SQUARE ROOT of 18 to get the actual hypotenuse which is 4.24. We use this procedure to find the magnitude of any vector by using its X and Y components to form a triangle with the vector itself as the hypotenuse. Hope this helps!
