Question

Help! I have tried several times to figure out this question on coordinates and turning counter clockwise from the x axis. My professors notes indicate I’m way off!

Answer 1

Given,

The coordinates (-5,-1.3)

To find

The polar coordinates,

Step-by-step explanation

The polar coordinates are written in the form

`(r,\theta)`

Thus,

`r=√((-5)^2-(-1.3)^2)=5.16`
`\begin{gathered} \theta=tan^(-1)(-(-1.3)/(-5)) \\ \Rightarrow\theta=-14.57^o \\ \Rightarrow\theta=360-14.57=345.43^o \end{gathered}`

Conclusion

The polar coordinates are

`(5.16,345.43)`
