This week, we learned many different types of ways to solve quadratic equations. You can solve quadratic equations with factoring, zero product law, using square roots and using the quadratic formula. While solving all the equations, I found that each… Continue Reading →

This week in Precalc 11, we learned a bunch of new things but solving radical equations were the hardest and most confusing for me. I’ve always struggled dealing with negatives, and obviously these radical equations had negatives. Working step by… Continue Reading →

This week in precalc 11, we started a new unit on absolute values and radicals. I learned that the absolute value can not be a negative number. The absolute value of a real number is defined as the principal square… Continue Reading →

For week 2, we mostly focused on geometric series, geometric sequences and infinite geometric series. I struggled more with these concepts than I did with arithmetic series and sequences. Working through the geometric sequences assignment, I came upon a word… Continue Reading →

For our first week of precalc 11, one of the things we learned were arithmetic series. An arithmetic series is the sum of the terms in an arithmetic sequence. An arithmetic sequence means that the difference between consecutive terms must… Continue Reading →
