text: 1. ## simplify the equation
  
  I need to simplify (i^2+2i+1)/(-i^2+1) to the form #i where # is any coefficient.

  Remember that $\displaystyle i^2 = -1$
  
  So,
  
  $\displaystyle \frac{i^2 + 2i +1}{-i^2 + 1}$
  
  $\displaystyle = \frac{-1 + 2i + 1}{1 + 1}$
  
  $\displaystyle = \frac{2i}{2}$
  
  $\displaystyle = 1i$ or just i
