## Step-by-step explanation

Problem to solve:

$Y^2-Y^1+Y+1=0$

Learn how to solve trigonometric equations problems step by step online.

$1+y^2=0$

Learn how to solve trigonometric equations problems step by step online. Solve the trigonometric equation y^2-y^1+y+1=0. Any expression to the power of 1 is equal to that same expression. Subtract 1 from both sides of the equation. Removing the variable's exponent. Calculate the power using complex numbers.

$y=i,\:y=-i$
