Find the coordinates of a point on the unit circle with an angle of $ frac{pi}{4} $ radians

Answer 1

Abigail Nelson

Joseph Robinson

First, we need to recall that the unit circle is a circle with a radius of 1 centered at the origin.

For an angle of $ \frac{\pi}{4} $ radians, we can use the sine and cosine functions to find the coordinates.

The x-coordinate is given by $ \cos( \frac{\pi}{4} ) = \frac{\sqrt{2}}{2} $.

The y-coordinate is given by $ \sin( \frac{\pi}{4} ) = \frac{\sqrt{2}}{2} $.

Therefore, the coordinates of the point are $ \left( \frac{\sqrt{2}}{2}, \frac{\sqrt{2}}{2} \right) $.

To find the coordinates of a point on the unit circle for an angle of $ frac{pi}{4} $ radians, we will use trigonometric functions.

The cosine function gives us the x-coordinate: $ cos( frac{pi}{4} ) = frac{sqrt{2}}{2} $.

The sine function gives us the y-coordinate: $ sin( frac{pi}{4} ) = frac{sqrt{2}}{2} $.

Thus, the coordinates of the point are $ left( frac{sqrt{2}}{2}, frac{sqrt{2}}{2}
ight) $.

The coordinates of a point on the unit circle for an angle of $ frac{pi}{4} $ radians can be found using trigonometric functions.

The x-coordinate is $ cos( frac{pi}{4} ) = frac{sqrt{2}}{2} $.

The y-coordinate is $ sin( frac{pi}{4} ) = frac{sqrt{2}}{2} $.

Therefore, the coordinates are $ left( frac{sqrt{2}}{2}, frac{sqrt{2}}{2}
ight) $.
