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?

  • @christopherellis2663
    @christopherellis2663 4 ปีที่แล้ว

    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.
