might have to google a picture of nemo's dad for c lol
I think c is a trick question XD he didn't specify which color stripes lol anyhoo, can you help me with the actual problems? cx
This is how i drew my graph may not be correct because currents confuse me sometimes. |dw:1443218314286:dw| this is kinda just for reference I think we just need to go ahead and find the x and y values for each vector and add them up.
how'd you draw the vectors?
I see now lol
so now I break them up into components like normal?
so ill make my lists |dw:1443218569870:dw|
yes break into components
grabbing calc brb
so the first set is the current, the second is the turtle, and the last is the fish?
wait.. why did you subtract 22 from 270?
wait.. nevermind cx I keep going back to the reference drawing and answering my own question XD
woe woe woe.. why is the second one 360?
(I checked the graph already too lol)
alright so considering its right on the x axis pointing to positive infinity you could say either cos(0) or cos(360)
why isn't it 180?..
and for the y values it would be the same value for sin(0) sin(360)
180 is on the x axis pointing towards negative infinity
all your x values turn negative and you y values stay 0 when the angle is 180
I don't know why this is so confusing for me :/ thanks for being patient.. but I don't understand
ill try to explain it
I'll be right back.. dinner is ready so I'm about to grab me some and I'll come back.
the angles i showed above will give you the same exact value lets use something from the question above .25m/s cos (335) = .227 if you say .25m/s cos(695) it also equals .227 the 695 came from (360+335)
oh okay I get it. the diagram helped XD
like how it is in the unit circle
alright so now to find the angle |dw:1443219938255:dw|
270-22 is 248, right? XD sorry, did it in my head. I just want to be sure
yes u did the math right lol
woe you're going to fast O.O give me time to catch up lol I'm slow XD
my bad just let me know if you have any confusions
wait im not sure i even needed to solve what i solved. the question isnt asking for this stuff *facepalm*
O.O so what do I do?
i think this was a simpler 2 part problem in which we subtract the current vector from the speed vector the for the turtle to find the speed of the turtle
I have to go :O thanks for the help.. I may come back tomorrow to ask for more help XD
then using the found speed of the turlte combine the vector of the fish
alright im sorry :/
it's okay XD I'm going to the football game. Thank you! you still have helped me understand a lot. talk to ya later!!
alright take care
@sweetburger sorry I haven't been on. Can you help me now?
