Questions: What point is symmetric with respect to the y-axis to the point (sqrt(2)/2, -sqrt(2)/2)?
Transcript text: What point is symmetric with respect to the $y$-axis to the point $\left(\frac{\sqrt{2}}{2},-\frac{\sqrt{2}}{2}\right)$ ?
Solution
Solution Steps
Step 1: Understand the concept of symmetry with respect to the \( y \)-axis
A point \((x, y)\) is symmetric to another point with respect to the \( y \)-axis if its \( x \)-coordinate is the negative of the original point's \( x \)-coordinate, while the \( y \)-coordinate remains the same. Mathematically, the symmetric point is \((-x, y)\).
Step 2: Identify the coordinates of the given point
The given point is \(\left(\frac{\sqrt{2}}{2}, -\frac{\sqrt{2}}{2}\right)\). Here, \( x = \frac{\sqrt{2}}{2} \) and \( y = -\frac{\sqrt{2}}{2} \).
Step 3: Apply the symmetry transformation
Using the symmetry rule, the symmetric point with respect to the \( y \)-axis is:
\[
\left(-x, y\right) = \left(-\frac{\sqrt{2}}{2}, -\frac{\sqrt{2}}{2}\right).
\]
