Answer
Question: Identify the surface defined by the equation \(-y^2-\frac{z^2}{2}+x^2=1\). Answer: The surface is a Hyperboloid of One Sheet.
1Step 1: Rewrite the given equation in standard form
First, let's rewrite the equation as: \(x^{2} - y^{2} - \frac{z^{2}}{2} = 1\)
2Step 2: Identify the type of surface
The given equation is similar to the standard form of a hyperboloid of one sheet which has the formula: \(\frac{x^{2}}{a^2} - \frac{y^{2}}{b^2} - \frac{z^{2}}{c^2} = 1\) Comparing the given equation with the standard form, we can see that \(a^2 = 1\), \(b^2 = 1\), and \(c^2 = 2\). Therefore, the equation represents a hyperboloid of one sheet.
3Step 3: Provide the final answer
The surface defined by the equation \(-y^{2}-\frac{z^{2}}{2}+x^{2}=1\) is called a Hyperboloid of One Sheet.
