Math 11

Week 6 – Precalc11

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 →

Week 5 – Precalc11

This week we didn’t learn very much that was new but we were introduced to a new unit called solving quadratic equations. We focused on factoring just like we did last year in grade 10 math. It was mostly review… Continue Reading →

Week 4 – Precalc11

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 →

Week 3 – Precalc11

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 →

Week 2 – Precalc 11

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 →

Week 1 – My Arithmetic Sequence

My arithmetic sequence : 4, 8, 12, 16, 20 (determine ) = + ( – )( ) = + ( – ) ( ) = + = Finding the sum of 50 terms :  =  ( + ) = (… Continue Reading →

Week 1 – Precalc 11

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 →
