Calculadora de valores de trigonometría
Used by developers, writers, and creators worldwide.
A trigonometry value calculator returns the sine, cosine, and tangent of any angle you enter in degrees. Type an angle and it converts to radians, computes the three core trigonometric ratios to six decimal places, normalises the angle into the standard zero to three hundred sixty degree range, and correctly reports tangent as undefined when the cosine is zero. Trigonometry describes triangles, waves, circular motion, and oscillations, so these values appear throughout geometry, physics, engineering, surveying, and computer graphics. Students use the tool to check homework and learn how the ratios change around the circle, while practitioners use it to grab a quick accurate value without a scientific calculator. Handling the undefined tangent case, where the cosine reaches zero, is something many quick tools get wrong, so the output stays trustworthy. Use it to evaluate a trig function or explore how the ratios behave.

FAQ
why is tangent sometimes undefined
Tangent equals sine divided by cosine, so wherever the cosine is zero, at 90 and 270 degrees and their equivalents, the division is undefined. The tool detects this and labels the result rather than showing a misleading huge number.
does it work with degrees or radians
You enter the angle in degrees, which the tool converts to radians internally before computing. It also reports the radian equivalent so you can use whichever unit your problem requires.
what does the equivalent angle line mean
Trig functions repeat every 360 degrees, so any angle has an equivalent between 0 and 360. The tool shows this normalised angle to help you relate large or negative inputs to a standard position on the circle.
