@danno @agent0smith

OpenStudy (agent0smith):

So you know the r from the last one right?

rebeccaxhawaii (rebeccaxhawaii):

http://prntscr.com/b7ba44

rebeccaxhawaii (rebeccaxhawaii):

okok

OpenStudy (agent0smith):

Now which quadrants?

rebeccaxhawaii (rebeccaxhawaii):

i get to pick? :D

OpenStudy (agent0smith):

lol well... sort of haha It tells you sin < 0 which is what quadrants?

rebeccaxhawaii (rebeccaxhawaii):

I, III, IV

rebeccaxhawaii (rebeccaxhawaii):

lets do the first quad

OpenStudy (agent0smith):

Wait. All students try cocaine. It tells you sin < 0 which is what quadrants?

rebeccaxhawaii (rebeccaxhawaii):

1,3,4 i said -.-

OpenStudy (agent0smith):

ALL students try cocaine. That's how you remember which ones are POSITIVE.

rebeccaxhawaii (rebeccaxhawaii):

BUT YOU SAID SIN IS NEGATIVE

rebeccaxhawaii (rebeccaxhawaii):

oh

rebeccaxhawaii (rebeccaxhawaii):

3 and 4

OpenStudy (agent0smith):

Good. NOW you do get to pick a quadrant from those.

rebeccaxhawaii (rebeccaxhawaii):

eenie meenie miney, catch a tiger by the toe. my mom says to count to ten, 1,2,3,4,5,6,7,8,9,10.

rebeccaxhawaii (rebeccaxhawaii):

so i pick 3

OpenStudy (agent0smith):

Okay. now what was r? from the pic earlier. You also get to pick either an x or a y value (keep in mind you're in quadrant 3). Pick any number as long as it's not bigger than r. use x^2 + y^2 = r^2 to find whichever you didn't pick (and again keep in mind... quadrant 3)

rebeccaxhawaii (rebeccaxhawaii):

r=6400

OpenStudy (agent0smith):

Look again at the pic.

OpenStudy (agent0smith):

r is how far the poor robot is from the center

rebeccaxhawaii (rebeccaxhawaii):

+3600

rebeccaxhawaii (rebeccaxhawaii):

6400+3600

OpenStudy (agent0smith):

Good, keep going with what i said

rebeccaxhawaii (rebeccaxhawaii):

10,000 is the r

rebeccaxhawaii (rebeccaxhawaii):

(-5,-10)???

OpenStudy (agent0smith):

Noooo noo no no no no. Go back to what I said.

OpenStudy (agent0smith):

You also get to pick *either* an x or a y value (keep in mind you're in quadrant 3). Pick any number as long as it's not bigger than r.

rebeccaxhawaii (rebeccaxhawaii):

(-5,y)

OpenStudy (agent0smith):

Okay but you could pick a much bigger value of x, but that's fine. But you could pick anything less than r...

rebeccaxhawaii (rebeccaxhawaii):

THAT'S WHAT I WANTED TO PICK EIUTHGRGIUFEGHFIJKRTEHIRB3 ok fine. (500, y)

OpenStudy (agent0smith):

Problem with picking 5 is it's so small that the other one will be nearly the same as r. Bigger is better. Okay good. Keep going. Last step. But oh you forgot it's in quad 3...

rebeccaxhawaii (rebeccaxhawaii):

(-500, y)

OpenStudy (agent0smith):

Good use x^2 + y^2 = r^2 to find whichever you didn't pick (and again keep in mind... quadrant 3)
