writing trig equations

sin60^circ= frac{x}{2}


tan A= frac{5}{9}


frac{sin20^circ}{90} = frac{sin B}{45}


a^2=b^2+c^2-2bccos A


a=sqrt{b^2+c^2-2bccos A}


angle A= 57^circ

June 1st

Plan for the day:

  • review of equation types and finding equations of lines
  • horizontal and vertical lines

By the end of class you will be able to:

  • graph a line quickly based on the form that the equation comes in
  • convert between different forms of the equation using algebra

Complete: lesson  5 and 6

Due:  Letter graph blog post

Math 9 Midterm Review

Here are some online sites to help with your exam preparations:

IXL  – choose the section that you need help with (there is a daily time limit without a paid subscription)

Thatquiz – exponents , algebra (choose simplify), geometry (choose surface area of cylinders and prisms), Arithmetic (fractions)

Quizlet:  the ones listed are created by Ms. Burton, you can search quizlet for more practice (or create you own!)


Stop Motion Animation – making math visual

Using the iPhone/ipad app iMotion the following was created:

Once yours is completed you’ll need to upload to OneDrive, your youtube channel or google drive and then copy the embed code from there to insert into your post.
