Determining Exponents of i By Drawing On Your Fingers!
มุมมอง 18211 ปีที่แล้ว
This is based around the "imaginary" number, i, which is equal to the square root of -1. i^1 = i i^2 = -1 i^3 = -i i^4 = 1 ...and then the pattern repeats. This video shows one way (of a large number of ways) to figure out the value of i taken to a large exponent. Enjoy! Need more math help?

you are genius my teacher at school she can't never expalin math you basically hit home on everything keep it up .
Not well explained
The isosceles is special only because of symmetry, and that the area is half of the product of the sides or of the height by the hypotenuse. Otherwise, it is just another right angled triangle. The ratio of the sides is of more interest than the angles between them.
This video just saved my life thankyou😂
Thank you, sir.
Way better than my math teacher
Really helped me since the day we were taught how to use the law of syllogism i wasn't paying attention
You look like john green
You are a literal blessing... I only wish I found you before I took the test.
Thank you dude i can ace my test now

i really appreciate i have a test tomorrow and i was so lost before i came here
thanks so much!! I'm learning geometry in a month and I've been warned about this chapter LOL, thanks so much :) better explanation than my teacher
Hey, why are you not singing this like the guy before you ? Please!
Thanks so much! This will definitely help with the ACT.
what a saint what a beautiful man

Thank you so much, I learned this from high school last two years, but now I forgot, my sis was sick and missed all week for school and now she asked me for help but never know how to solve these, I am so happy that she got it and I reminded myself how to solve these again. your explanations are so easy to get. I appreciate your support so much!
Sweet video, this teacher walks you through the steps of each example very nicely, has a clear voice, and explains very well.
Thank YOU ! It helped me study for my math test :)
