"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 »
