This week in pre calculus 11 we spent almost the whole week learning different methods to solving quadratic equations. A quadratic equation will always be an equation with a degree of 2 (). When working with quadratic equations you need to remember the zero product law: if you multiply 2 numbers and get a product […]

Week 5 – Pre Calculus 11
This week we only did one lesson because we had our unit test. The lesson we learnt brings a lot of the stuff we learnt in grade 10 back into our heads. Solving Quadratic Equations, is basically factoring from grade 10 except a bit more difficult. When solving these equations there are a few steps you […]
Week 4 – Pre Calculus 11
This week I chose to talk about adding and subtracting radical expressions. When adding and subtracting radicals there are a few key things to remember… Before doing any adding or subtracting you must make sure all the radicals are in the simplest form possible, that way it makes it pretty easy for the person doing […]
Week 3 – Pre Calculus 11
This week in class we learnt about absolute values, the definition of an absolute value is the principal square root of a square of a number. Another way to simply describe an absolute value is the distance a number is from 0 on the number line. For example |5| = 5 because it is 5 […]
Week 2 – Pre Calculus 11
This week we learnt about geometric sequences. It is somewhat similar to arithmetic sequences although instead of having a difference, the numbers are multiplied by a constant common ratio (r). The regular formula for calculating terms within the sequences is: =a While I was doing my weekly assignment, it was going pretty good. I was […]
Week 1 – Arithmetic Sequence
4, 9, 14, 29, 34… =? = + (n – 1) (d) = 4 + 49 (5) = 4 + 245 = 249 = ( + ) = (4 + 249) = 25 (253) = 6325
Week 1 – Pre Calculus 11
The topic I am choosing to write about this week in math is something called “Arithmetic Series”. A short explanation of what arithmetic series are, is basically when you have a regular sequence but need to add all the number in the sequence together to find the sum (Ex. Sn =) So, if your sequence […]
