12.4-bo'lim: To'rtburchak yuzalar

Quyidagi kvadrat yuzalarning har birini chizing.

1. \(\displaystyle \frac{{{y^2}}}{9} + {z^2} = 1\) Yechim
2. \(\displaystyle \frac{{{x^2}}}{4} + \frac{{{y^2}}}{9} + \frac{{{z^2}}}{6} = 1\) Yechim
3. \(\displaystyle z = \frac{{{x^2}}}{4} + \frac{{{y^2}}}{4} - 6\) Yechim
4. \({y^2} = 4{x^2} + 16{z^2}\) Yechim
5. \(x = 4 - 5{y^2} - 9{z^2}\) Yechim
