    rectangular to spherical coordinates equation Problem

    rectangular to spherical coordinates equation Problem-capture.png
    I am stuck on trying to convert this.

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

    Re: rectangular to spherical coordinates equation Problem

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

    $z=\rho \cos \theta$

    Plugging in:

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

    Re: rectangular to spherical coordinates equation Problem

    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.

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