  • exam coming up on this stuff... this stuff sucks

  • @fahdiqbal11 You missed a spot there, ranger, don't be so sure about your claim. Notice that z = -r != r => (...) => tan(phi)=-1 => phi = -pi/4 = 3pi/4

  • z=sqrt x^2 + y^2

    z=r

    rhocosphi=rhosinphi divide both sides by rho

    cosphi=sinphi divide both sides by cosphi

    1 = tanphi

    phi = arctan 1

    phi= pi/4

    NOT 3pi/4

  • Perfect!

  • THANK YOUUUUUUUU!!!!!!

    

  • @parpsy because you measure it from the positive z axis.

  • why three pie over four explain phi more

  • @TomRiverstone When you have z = a*sqrt(x^2 + y^2) it is tan(phi) = 1/a

  • @sunrise3500 it equals p^3, but when you multiply by the volume element you get p^5... (comes from p^2 sin )
