Scribe Post

welcome back to school everyone. I hope everyone had a great break.

For the new term and new section (trigonometry) we are going to need new supplies

everyone needs to have there trigonometry book we got in the beginning of last semester, you will need a ruler, a graphing calculator, a notebook and graph paper make sure to bring all this everyday or you will lose points.

Today we started off the term by talking about cartesian coordinate systems.

we compared the street layout of boston and manhattan. manhattan was much easier to see a way around because of its street layout being a coordinate system,

we finished off class by learning about the distance formula. this formula is derived from pythagoreans theorem so it has the same basic idea. its is the square root of delta X squared + delta y squared =d

the term delta is represented by a triangle and mean the difference of the start and finish.

so in this setting it is the difference of the starting x coordinate and the finishing x coordinate squared + the difference of the starting y coordinate and the finishing y coordinate. therefore it would be X1-X2 squared + Y1-Y2 squared then take the square root of all =d

And that is all for today

enjoy the year
