In a right triangle, the trigonometric functions are: sine θ =opposite/hypothenusecosine θ =adjacent/hypothenusetangent θ =opposite/adjacent trig·o·no·met·ric function (trĭg′ə-nə-mĕt′rĭk) A function of an angle, as the sine, cosine, or tangent, whose value is express...

The trigonometric functions can help solve for missing sides and angles in a triangle. Often, the Pythagorean Theorem is also useful to find the length of missing sides. The Pythagorean Theorem is a2+b2=c2 where a and b are the leg lengths of a right triangle and c is the length of ...
🙋 To know how to calculate or evaluate these inverse functions, visit our inverse sine, inverse cosine, and inverse tangent calculators. Let's use the following triangle to explain how this calculator solves for the different sides and angles according to the information known. Using two sides...
Learn about the unit circle in trigonometry. Understand the use of the unit circle to find the trigonometric functions. See how to find sine and...
Trig functions are functions that take an angle as the argument. We define these functions by using the angle of a right triangle that is inserted in a unitary circle. Then, we relate that angle to the sides of such a triangle. As the right triangle is circumscribed in a unit circle, ...
All trig functions operate on radians, an angular unit in which radians measure a full revolution. : Math « Development « Flash / Flex / ActionScript
Reciprocal trigonometric functions The reciprocal functions of the sine, cosine, and tangent are, respectively, thecosecant,secant, and thecotangent. They are of limited practical use nowadays, given our calculation capabilities, but are still a part of the school curriculum in high schools and univ...
It would be strange if, after rotation, the original colors (functions) pointed the same way.The change must be based on the other function in the triangle (sine's change is based on cosine, cosine on sine, tangent on secant, etc.)...
The hexagon also shows that a function between any two functions is equal to them multiplied together (if they are opposite each other, then the "1" is between them):Example: tan(x)cos(x) = sin(x) Example: tan(x)cot(x) = 1
