Quantum Computing: Angle referred to with \theta symbol instead of \alpha symbol (page 402)

Title: Quantum Computing: Angle referred to with \theta symbol instead of \alpha symbol (page 402)
Example: Quantum Computing - Under the section titled Writing the Quantum State Using Polar Coordinates, the text states “…so \theta is 20\pi/180 = \pi/9 radians.”. Shouldn’t it be “”…so \alpha is 20\pi/180 = \pi/9 radians.“” or am I just confused? (page 402)
Thank you in advance.

Hi,
Yes, you are correct. It should be “… \alpha is 20\pi/180 = \pi/9 radians.”
Thanks for pointing out.
