This week we review polynomials. Something new I learned thought was how to do an Area Diagram. How do to it is by draw a box with boxes inside it. Then you have to put your equation on the side and top. For example, the picture is a monomial so it has four boxes with C and D at the top and A and Bon the side. Next you have to multiply AxC, AxD, BxC, BxD. then after you distribute the same property.
In the chemistry unit, the core competencies skills I used was Critical thinking. I used this because I had to anaylize, critique and develop questions when I work on the practice problems and when I work on equations. I also used Communication when we did our lab.
This week we didn’t really learn anything new it was just review on what we did during week 4. Something we did was using a scientific calculator to solve the questions. How to use a scientific calculator for trigonometry is by punching in cos, sin, or tan and entering the number after and if you need to use -1 you enter the shift button before.
This week we learned trigonometry. Trigonometry is finding angles and lengths of a triangle with SOH (Sin=opposite over hypotenuse) CAH Cos= opposite over hypotenuse TOA tan= opposite over adjacent
. 
This week it was mainly just review of polynomials. Some new things I learned was different terms for different polynomials like monomial which is when there is 1 term, binomial when there is 2 terms, and trinomials when there is 3 terms. If there is 4 or more terms it is just called a polynomials.

I also learned different names for different degrees of polynomials
Constant= degree of 0
Linear=degree of 1
Quadratic=degree of 2
Cubic=degree of 3
Quartic=degree of 4
Quintic=degree of 5
the degree is the exponent on the variable.
This week I learned how to do exponent laws. We learned the product law, quotient law, and power law. The product law is where you add the exponents together, quotient is where you subtract the exponents and power law is where you multiply.
