In math, the sine of an angle is defined as the length of the side of a right triangle opposite the acute angle divided by the length of the hypotenuse. The lengths of these sides can be determined through the Pythagorea... More »

The sine of a 10-degree angle is 0.17. The sine is defined as the length of the side of the triangle opposite the angle in question, divided by the length of the hypotenuse. These lengths can be determined through the Py... More »

The six trigonometric functions are the sine, cosine, tangent, cosecant, secant and cotangent. The functions are used to find a ratio between the sides of a right triangle when given one angle. They are used to evaluate ... More »

"Cot" is the abbreviation for "cotangent," a trigonometric function used to find the value of an angle in a right triangle by dividing the length of an adjacent side by the length of the opposite side. The numerical valu... More »

The law of sines states that, for any given triangle, the ratio of the length of a side divided by the sine of the opposite angle is equal to the same ratio of the other two sides and angles. The law of sines is part of ... More »

The trigonometric functions sine, cosine and tangent calculate the ratio of two sides in a right triangle when given an angle in that triangle. To find the cosine of angle pi, you need graph paper. More »

The basic trigonometric functions sine, cosine, and tangent give the ratio between two sides of a triangle with a given angle. The inverse trig functions find the angle if the ratio is known. Finding the inverse cosine o... More »
