# Thread: rectangular to spherical coordinates equation Problem

1. ## rectangular to spherical coordinates equation Problem

I am stuck on trying to convert this.

I am stuck since I can find any values for theta or phi.

2. ## Re: rectangular to spherical coordinates equation Problem

$y=\rho \sin \theta \sin \varphi$

$z=\rho \cos \theta$

Plugging in:

$\rho=\tan^{1/5} \theta \sec \theta \sin^{1/5} \varphi$

confused. isn't z=pcos(phi)? But , i got the answer by switching the the theta and phi. Thanks though!

Yes, it was a typo. I am not sure why it would be confusing. Typos happen from time to time.

$$\rho = \sin^{1/5} \theta \sec \varphi \tan^{1/5} \varphi$$

Just making sure! I had to google cause im still unfamiliar with the coordinate system. Thank you !
