InCA Assignment for 2/5

We finished More work with imaginary numbers today, in particular simplifying expressions that involve multiplying them or with higher powers. We saw in the videos we watched previously that powers of i don’t increase like other real numbers, but instead cycle through the numbers 1, i, -1, -i, and then back to 1 again.

We also discussed briefly how these new numbers work with allowing us to solve previously unsolvable quadratic equations, which we will reinforce tomorrow.
