He didn’t mention this before the video ended, but I’m pretty sure m2 and m1 can be switched as you wish. This is because for multiplication, two terms can always be switched, and achieve the same result, and for subtraction, it will come out to -x or x, both of which will give you the same final number. You can then just turn the x positive, because you cannot have a negative angle (not really).
Take the magnitude of the answer or just let your first gradient to be bigger than the second one in working scenarios in order to obtain a positive result
Everytime I see teacher' s videos I get my exact questions with its answer. Thanks Teacher
morning grab a sheet
😂😂
Can |arctan(m1)-arctan (m2)| be used?
So...
Which one do you put first?

Also note, most versions of this formula online include absolute value around the whole equation, for the reason I mentioned about subtracting.
@@roguetrin8897 thx bro
damn 10 years ago
what if i take the unknown slope as m2 instead of m1? does the answer change?

@@kpoglu5063 thanks :)
Thanks, ur videos are really helpful :) Great teacher
So this is where that formula comes from
Just from the tan trig identity
thank u sir 🥹🙌🏻
Thx bro
nice but too blonde u need a change of the board pe n
thanks
