(8,23 degrees) = (r, theta) r = 8 theta = 23 degrees ------------------------------ x = r*cos(theta) x = 8*cos(23) x = ??? y = r*sin(theta) y = 8*sin(23) y = ??? The answer will be in the form (x,y)

hmm..
jim_thompson5910
  • jim_thompson5910
all you have to do is evaluate 8*cos(23) and 8*sin(23) using a calculator

  • anonymous
i go -0.5

All you have to do now is simply use your calculator. Make sure it's in degree mode. You can use the same method for the others
anonymous
  • anonymous
ok..can you set the other ones up?
Hero
  • Hero
You use the same exact method on the others. Well, the third one actually doesn't have a vertical component. But you probably already knew that.
anonymous
  • anonymous
no.. i didnt.
shamim
  • shamim
ok i wanna try 3rd problem
shamim
  • shamim
here r=5
shamim
  • shamim
\[here \theta=180\]
Hero
  • Hero
x = -5 y = 0
shamim
  • shamim
x=rcos180=5cos180=5(-1)=-5

This stuff is cake compared to University level
shamim
  • shamim
and y=rsin180=5sin180=5(0)=0
shamim
  • shamim
did u get my solution
Hero
  • Hero
Bro, you didn't need to write all of that. And no, she doesn't get it.
shamim
  • shamim
ok
shamim
  • shamim
i need graphical representation to make it clearer
Hero
  • Hero
There, we helped you with the 1st one and the third one @lalaloopsey . Now do the second one on your own.
