(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)

- anonymous

hmm..

- jim_thompson5910

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

- anonymous

i go -0.5

- anonymous

got*

- jim_thompson5910

for which one, 8*cos(23) or 8*sin(23) ?

- anonymous

DamnImBad

- anonymous

do you know the answers?

- anonymous

Nope, I don't remember how to do this

- anonymous

@jim_thompson5910 gae u the fomula all you have to do is finish the problem

- Hero

- anonymous

answer my questions then..

- anonymous

@Hero

- Hero

I'll see what I can do, but unblock me

r = 8

- Hero

x = 8 cos (23)
y = 8 sin (23)

- Hero

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

ok..can you set the other ones up?

- 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

no.. i didnt.

- shamim

ok i wanna try 3rd problem

- shamim

here r=5

- shamim

\[here \theta=180\]

- Hero

x = -5
y = 0

- shamim

x=rcos180=5cos180=5(-1)=-5

- Hero

High Schoolers have it so easy

- Hero

This stuff is cake compared to University level

- shamim

and y=rsin180=5sin180=5(0)=0

- shamim

did u get my solution

- Hero

Bro, you didn't need to write all of that. And no, she doesn't get it.

- shamim

ok

- shamim

i need graphical representation to make it clearer

- Hero

There, we helped you with the 1st one and the third one @lalaloopsey . Now do the second one on your own.
