NEEED HELP WITH A A TRIGONOMETRY QUESTION

Question

CONVERT TO RECTANGULAR COORDINATES.

(R,THETA)= (5.150DEGREES)

 

Answer 1

If r = 5 and θ = 150°, then x = rcosθ = -5√3/2

 

                                        y = rsinθ = 5/2

 

Rectangular coordinates:  (-5√3/2, 1/2)

Answer 2

Just in case you meant to say (5.1, 50°), the answer is

 

x = r cosθ = 5.1 cos50° = ?

y = r sinθ = 5.1 sin50° = ?

Answer 3

Hi Ursula,

 

Is your question

 

(R,THETA)=(5.15 , 0 DEGREES)

 

It seems to me that you missed the comma after 5.15 and THETA is 0 degrees.

 

If that is the case, the answer is

 

x=5.15

y=0.00

 

In other words (x,y)=(5.15,0.0)

 

If that is the case, please review the question and ask it again.

 

I hope this helps you.
