Questions tagged [radians]

Questions regarding angular sizes, arguments for trigonometric functions geometry etc.

Radian is a unit of angular measure. It is measured as the ratio between the length of the corresponding arc and its radius. It is often used as an argument to trigonometric function (e.g., sin, cosine etc.). It is also used as an angular measure for frquency analysis of signals (e.g., in Fourier space).

Java is outputting the wrong value for a Math.tan() calculation

Here is the code from both classes, the user has to input the value for two angles and a length for part of a triangle. I understand Java uses radians, but even with a simple conversion either using Math.toDegrees or * 180/Math.Pi it still gets the…

Why Java Math.toRadians() is not accurate and how to solve it?

I'm creating own Turtle app similar to python in Java. The angles taken in the instructions is in degrees. While drawing it, I have to use sin and cos which requires the angle to be in radians. So, I used Math.toRadians(theta). My instructions are…
