Love your ruler, Mr.English man.
Thank you for uploading this!

@Ezunit1991 The hypotenuse can never be opposite, because the hypotenuse is always opposite the 90 degree angle in a right triangle, and therefore can never be opposite of one of the two acute angles.
just look up soh cah toa if you want to know when to use sine, cosine, or tangent.
-
how did you know to use tan? why not sin or cos? what if the hypot is opposite?
-
how do you know which angle to find i mean why is the angle at the right and not the one down? please reply! i know how to do pythagoras theorem and trig to figure it out but i get confused WHICH angle to choose?
-
you were mindblowing...!!!!!!!!!!
-
Why Tan THETA and Don't you have a video of subtracting vectors ! ?
-
Why Tan Theta ?
-
its 632.45
therefore it should be 632.5.... not 632.4 km/h
-
WTF
-
@davidallany1 you had to use inverse tan because it was we had to find the angle. whenver you need to find the angle you have to use inverse of the ratio.

thanks so much you explain it far better than my physics teacher.
could you pleaaaaase do more videos on AS physics especially forces and motion ... i'm failing physics :( please :(
i beg you!
