Happy New Year from MrBillDoesMath!

Answer:

 i ^ (2n) = (i^2)^n = (-1)^n = -1 if n is odd and = 1 if n is even

 i ^ (2n+1) = i^(2n)* i =     -1 * i = -i if n is odd and =  1*i = i if n is even


Not sure if this answers your question but hopefully pushes you n the right direction.


Thank you,

What is the equation of the quadratic graph with a focus of (−4, seventeen eighths ) and a directrix of y = fifteen eighths
Lunna [17]
Standard form for a parabola:
( x - h )² = 4 p ( y - k )
Vertex: ( h, k ) = ( -4, 2 )
Displacement from vertex to focus:
p = 2/8 = 1/4
( x + 4 )² = 4 · 1/4 ( y - 2 )
y = ( x + 4 )² + 2
or general form: 
x² + 8 x - y + 18 = 0
