Just Chill & Rotate By 90°

Just Chill & Rotate By 90°
This is what happens when math nerds get creative! The cartoon dog is placed on the complex plane, rotating through the values of i (the imaginary unit). When you multiply any number by i , it rotates 90° counterclockwise on the complex plane. That's why our chill doggo is making a full circle through 1, i , -1, and - i . It's basically the mathematical version of "look what they need to mimic a fraction of our power" because regular folks use boring old degrees for rotation while mathematicians use imaginary numbers . Next-level flex! 💪
