This week in math 11 we learned about the discriminant of the quadratic formula. This is the part of the formula that is under the root symbol, it is . You would use this part of the equation when you are asked to find out how many solutions an equation has. You use it the same as the original formula…

Week 6 – Math 11
This week in math 11 we learned how to solve quadratic equations. Along with this we learned a few different ways to do so, I am going to be talking about is completing the square. This is how this method works… The rule to follow is, To complete the square of … half the middle coefficient, then square it. For…
Week 5 – Math 11
This week in math 11 we learned how to factor polynomials. This is something that we learned in math 10, so we already knew the basics, now we are just growing our knowledge. We were taught the acronym C.D.P.E.U, this stands for Common, Difference of squares, Pattern, Easy and Ugly. One thing to keep in mind is that C &…
Week 4 – Math 11
This week in math 11 we learned about how to multiply radicals. Multiplying radicals sounds a lot harder than it it because everything we need to know we have already learned. One of the key word to remember is Expand, this word means to distribute. Distributing means to multiply a number on the outside of the brackets by the numbers…
Week 3 – Math 11
This week in math 11 we learned about the Absolute Value of a Real Number and the use of absolute value bars. Absolute value bars are 2 vertices lines “| |” that go on either side and indicate that you will need to find the absolute value of the number inside. These bars can get commonly confused with brackets “()”…
Week 2 – Math 11
This week in math 11 we learned about diverging and converging geometric sequences. When determining whether or not a sequence is diverging or converging you will look at the r value, if this r value is greater than 1 (r > 1) or if its less than -1 (r <-1) then that means its diverging. Diverging sequences grow at a…
Week 1 – My Arithmetic Sequence
Find and 11, 18, 25, 32, 39… 18-11=7 25-18=7 32-25=7 39-32=7 d=7
Math 11 – Week 1
This week in math 11 we learned about Arithmetic Sequences. An arithmetic sequence is and arrangement of numbers changing at the same rate. Learning how arithmetic sequences work comes in ver handy for finding values of numbers further down the chain without having to count them all one by one. The formula for arithmetic sequences allows you to use the…
