The Trignometric Table of sin, cos, tan, cosec, sec, cot is useful to learn the common angles of trigonometrical ratios from 0° to 360°. Select degrees or radians in the drop down box and calculate the exact cot 120° value easily Our cotangent calculator accepts input in degrees or radians, so once you have your angle measurement, just type it in and press calculate. Alternatively, if the angle is unknown, but the lengths of the two sides of a right angle triangle are known, calculating the cotangent is just a matter of dividing the adjacent by the opposite side
The cot of -120 degrees is √(3)/3, the same as cot of -120 degrees in radians. To obtain -120 degrees in radian multiply -120° by $\pi$ / 180° = -2/3 $\pi$. Cot -120degrees = cot (-2/3 × $\pi)$. Our results of cot-120° have been rounded to five decimal places. If you want cotangent -120° with higher accuracy, then use the calculator below; our tool displays ten decimal places 1 Answer.

In a right triangle, the cotangent of an angle is the length of the adjacent side divided by the length of the opposite side. In a formula, it is abbreviated to just 'cot'. Of the six possible trigonometric functions, cotangent,secant, and cosecant, are rarely used Cotangent is a trigonometric function abbreviated cot.Use the formula below to calculate the cotangent of an angle. Cotangent Formula. The cotangent formula is: cot(α) = adjacent b opposite a Thus, the cotangent of angle α in a right triangle is equal to the length of the adjacent side b divided by the opposite side a.. To solve cot, simply enter the length of the adjacent and opposite sides.
In other words, it could be referred to as the cos(x) divided by the sin(x). [Cosine/Sine]. The ratio of the adjacent side of an angle to its opposite side is termed as the cotangent. cot x = tan-1 (x) or cot x = cos(x)/sin(x) Make use of the below cot x or cotangent calculator to find the cot of an angle in degrees and radians Trigonometric table tangent cotangent in degrees - it is the four-valued table of tangents and cotangents in degrees within one minute.

If you take that distance and multiply it by the cotangent of 20 degrees (the angle you determined with your compass), that will tell you distance between you and the house. And since you probably don't know the cotangent of 20 degrees by memory, you just have to refer to the handy cotangent table on the back of your KB-14 List of trigonometric identities 2 Trigonometric functions The primary trigonometric functions are the sine and cosine of an angle. These are sometimes abbreviated sin(θ) andcos(θ), respectively, where θ is the angle, but the parentheses around the angle are often omitted, e.g., sin θ andcos θ. The tangent (tan) of an angle is the ratio of the sine to the cosine * Statement of the given problem, * * As the measure of an acute angle in a right triangle increases, will the value of the cotangent of the angle increase or decrease? * Let θ denotes the concerned acute angle in the given right triangle. * Acc.. Let the angle be A. If sinA = 3/5 = 0.6 then cos²A = 1 - sin²A = 1 - 0.36 = 0.64 cosA = 0.8 cotA = cosA/sinA = 0.8/0.6 cotA = 4/3 This holds for acute angle A.

The Law of Cosines states that the square of any side of a triangle is equal to the sum of the squares of the other two sides minus twice the product of the other two sides and the cosine of the included angle. For triangles labeled as in (Figure), with angles α,β, α, β, and γ, γ, and opposite corresponding sides a,b, a, b, and c, c. Using the unit circle diagram, draw a line tangent to the unit circle where the hypotenuse contacts the unit circle. This line is at right angles to the hypotenuse at the unit circle and touches the unit circle only at that point (the tangent point). Extend this tangent line to the x-axis. The distance of this line segment from its. Radians are another way of measuring angles, and the measure of an angle can be converted between degrees and radians. Learning Objectives. Cotangent can also be calculated with values in the unit circle. Applying the [latex]x[/latex]- and [latex]y[/latex]-coordinates associated with angle [latex]t[/latex], we have. Properties of the number. It's approximately 54.9 million and has 2 divisors.

Tangent is nothing but division of sine and cosine functions. Tan (x) = Sin (x) / Cos (x). In a right angled triangle, tangent angle is division of opposite angle and adjacent angle. Substitute the values in the formulae to get the tan value. Use Tan (A+B) and Tan (A-B) formulas. Convert the given angle to the nearest common value How to Find a Reference Angle in Degrees Finding a reference angle in degrees is straightforward if you follow the correct steps. 1. Identify your initial angle. For this example, we'll use 440° 2. The angle is larger than a full angle of 360°, so you need to subtract the total angle until it's small. 440° - 360° = 80° 3 The negative tangent of 120 degrees is equal to the tangent of 120 degrees.
