What is csc cot and SEC?
What is Csc Sec Cot? Csc sec cot are the three trigonometric functions cosecant, secant, and cotangent respectively. These functions are also called the reciprocal trigonometric functions as they are the reciprocals of the sine function, cosine function, and tangent function, respectively.
How do you find csc cot and sec?
The cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x . The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x . = tan 5π 4 .
What is sec and csc equal to?
For example, csc A = 1/sin A, sec A = 1/cos A, cot A = 1/tan A, and tan A = sin A/cos A.
What is cot equal to?
In trigonometry, cot or cotangent is one of six trigonometric ratios. In a right-angled triangle, cot of an angle is equal to the ratio of adjacent side and opposite side of angle. Cot x is also equal to the reciprocal of tan x.
What is cotangent used for?
Cotangent is used the same way the sine, cosine, and tangent functions are used. You can use them based on a right triangle, using the opposite and adjacent sides of the triangle, or you can use it based on the unit circle, which shows the angles in radians.

What is the value of SEC?
The secant of angle zero degrees is written as in Sexagesimal system and the exact value of secant of angle zero degrees is equal to one.
How do you calculate cot?
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. For example, if in the illustration above b = 6 and a = 12, then cot(α) = 6 / 12 = 0.5.
How do you find SEC?
The secant of an angle in a right triangle is the value found by dividing length of the hypotenuse by the length of the side adjacent the given angle. The secant ratio is the reciprocal of the cosine ratio.
What is csc?
The cosecant ( csc ) (csc) (csc)
The cosecant is the reciprocal of the sine. It is the ratio of the hypotenuse to the side opposite a given angle in a right triangle.
What is cot of an angle?
In a right angled triangle, the cotangent of an angle is: The length of the adjacent side divided by the length of the side opposite the angle. The abbreviation is cot. cot(θ) = adjacent / opposite. It is not commonly used, and is equal to 1/tangent.
What does cot stand for in math?
The short name for cotangent. It is the length of the adjacent side divided by the length of the side opposite the angle in a right-angled triangle. cot(θ) = adjacent / opposite. (Note: the tangent function tan(θ) = opposite / adjacent) See: Cotangent.
What is a sec math?
In a right angled triangle, the secant of an angle is: The length of the hypotenuse divided by the length of the adjacent side. The abbreviation is sec. sec(θ) = hypotenuse / adjacent.
What is csc on a calculator?
In a right triangle, the cosecant of angle α, or csc(α), is the ratio between the angle’s opposite side and the hypotenuse. Cosecant is a trigonometric function abbreviated csc.
What is sec Trig?
Secant (sec) – Trigonometry function
In a right triangle, the secant of an angle is the length of the hypotenuse divided by the length of the adjacent side. In a formula, it is abbreviated to just ‘sec’. sec.
What is the value of cos?
The value of cos 1 degrees can be calculated by constructing an angle of 1° with the x-axis, and then finding the coordinates of the corresponding point (0.9998, 0.0175) on the unit circle. The value of cos 1° is equal to the x-coordinate (0.9998). ∴ cos 1° = 0.9998.
What is the value of cot 0?
The value of cot 0 degrees is undefined(∞).
What does cot theta equal?
The reciprocal sine function is cosecant, csc(theta)=1/sin(theta). The reciprocal tangent function is cotangent, expressed two ways: cot(theta)=1/tan(theta) or cot(theta)=cos(theta)/sin(theta).
What is inverse sec equal to?
Sec Inverse x is the inverse trigonometric function of the secant function. Mathematically, it is denoted by sec–1x. It can also be written as arcsec x. In a right-angled triangle, the secant function is given by the ratio of the hypotenuse and the base, that is, sec θ = Hypotenuse/Base = x (say).
What is the value of cosec?
The value of cosec 0 degrees is undefined(∞). Cosec 0 degrees in radians is written as cosec (0° × π/180°), i.e., cosec (0π) or cosec (0).
What is the full form of cot?
COT – Carry Over Transactions.
How do you write cosecant?
Cosecant is one of the main six trigonometric functions and is abbreviated as csc x or cosec x, where x is the angle. In a right-angled triangle, cosecant is equal to the ratio of the hypotenuse and perpendicular. Since it is the reciprocal of sine, we write it as csc x = 1 / sin x.
How do you write a sec function?
The secant function or sec function can be defined as the ratio of the length of the hypotenuse to that of the length of the base in a right-angled triangle. It is the reciprocal of cosine function and hence, is also written as sec x = 1 / cos x.
