What is the reciprocal of csc?
The reciprocal identities are: csc(x) = 1/sin(x), sec(x) = 1/cos(x), and cot(x) = 1/tan(x).
What does csc equal to?
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 .
Is sine the inverse of cosecant?
Inverse Reciprocal Trigonometric Functions
We already know that the cosecant function is the reciprocal of the sine function. This will be used to derive the reciprocal of the inverse sine function. … The inverse reciprocal identity for cosine and secant can be proven by using the same process as above.
Why is the reciprocal of sine cosecant?
Since sine function is the ratio of the lengths of the opposite side to the angle in consideration and hypotenuse in a right-angled triangle, the reciprocal of sine is the ratio of the hypotenuse and the opposite side of a right-angled triangle which is the formula for the cosecant function.
How do you write cosecant?
Cosecant (csc) – Trigonometry function
In a right triangle, the cosecant of an angle is the length of the hypotenuse divided by the length of the opposite side. In a formula, it is abbreviated to just ‘csc’.

What gives Cosec?
When the length of the hypotenuse is divided by the length of the opposite side, it gives the Cosecant of an angle in a right triangle. It is denoted as Cosec and sometimes as csc. It is one of the trigonometric functions, in trigonometry.
What is csc?
A CSC is essentially a kiosk with a personal computer, a wireless connection and other equipment. Through computer and Internet access, the CSCs provide multimedia content related to e-governance, education, health, telemedicine, entertainment and other government and private services.
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.
How do you find inverse sine?
To find the inverse of an equation such as sin x = 1/2, solve for the following statement: “x is equal to the angle whose sine is 1/2.” In trig speak, you write this statement as x = sin–1(1/2). The notation involves putting a –1 in the superscript position.
How do I know if I have SOH CAH TOA?
- SOH = Sine is Opposite over Hypotenuse.
- CAH = Cosine is Adjacent over Hypotenuse.
- TOA = Tangent is Opposite over Adjacent.
Does sine go with cosecant?
Cosecant is the reciprocal of sine. Secant is the reciprocal of cosine.
Why is it named cosecant?
Logically, its complement was called the cosecant, which is the reciprocal of the sine. It has to do with how the secant was historically defined. If you take a look at the unit circle, the secant is the distance from the center to the vertical tangent in a certain direction.
What does tan 45 mean?
tan(45∘)=1.
Where is cot on ti84?
Press 2nd MATH to enter the MATH popup menu. Press A to enter the Trig submenu. Press 6 to select cot(.
What is cosecant and example?
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 cosec formula?
The cosecant formula is given as follows: cosec A = hypotenuse / opposite side = AB / BC = c / a. We know that, sin A = opposite side / hypotenuse.
What is csc exam?
The Canadian Securities Course is an exam conducted by the Canadian Securities Institute (CSI) for individuals interested in trading securities or providing investment advice. It consists of two multiple-choice exams that must be completed within one year of registration.
How difficult is the csc exam?
It is not up there with university level exams so you could say it is easy. It’s not very hard. If you come from an accounting or finance background it should be easy. Otherwise, just read the books and practice the online questions.
Does cosecant have an amplitude?
The period of both secant and cosecant is 2π like sine and cosine. There is no amplitude for secant and cosecant, but there is a vertical stretch that is used instead.
What is sin2?
The value of sin 2 degrees is 0.0348994. . .. Sin 2 degrees in radians is written as sin (2° × π/180°), i.e., sin (π/90) or sin (0.034906. . .).
What is the inverse sine of 2?
Sine | Angle (degrees) | Angle (radians) |
---|---|---|
12 | 30° | π6 |
√22 | 45° | π4 |
√32 | 60° | π3 |
√6 + √24 | 75° | 5π12 |
What is the inverse of cosine?
The inverse cosine function is written as cos^-1(x) or arccos(x). Inverse functions swap x- and y-values, so the range of inverse cosine is 0 to pi and the domain is -1 to 1. … So y equals cosine x for x between 0 and pi that’s the restricted cosine function it is 1 to 1 and so we can invert it.
Which is opposite adjacent and hypotenuse?
In a right triangle, the hypotenuse is the longest side, an opposite side is the one across from a given angle, and an adjacent side is next to a given angle. The hypotenuse of a right triangle is always the side opposite the right angle. …
Can you use Sohcahtoa on any triangle?
Q: Is sohcahtoa only for right triangles? A: Yes, it only applies to right triangles. … A: They hypotenuse of a right triangle is always opposite the 90 degree angle, and is the longest side.
What is the shortest side of a 30 60 90 triangle?
And so on. The side opposite the 30° angle is always the smallest, because 30 degrees is the smallest angle. The side opposite the 60° angle will be the middle length, because 60 degrees is the mid-sized degree angle in this triangle.
What is the reciprocal of sine called?
There are three reciprocal trigonometric functions, making a total of six including cosine, sine, and tangent. The reciprocal cosine function is secant: sec(theta)=1/cos(theta). The reciprocal sine function is cosecant, csc(theta)=1/sin(theta).
What is reciprocal in math?
The reciprocal of a number is the number you would have to multiply it by to get the answer 1. … Another interesting point is that the reciprocal of a reciprocal is the original number.
How do you graph cosecant?
Drawing the cosecant curve by using the sine as a guide. The cosecant goes down to the top of the sine curve and up to the bottom of the sine curve. After using the asymptotes and reciprocal as guides to sketch the cosecant curve, you can erase those extra lines, leaving just y = csc x.
What is a sin in math?
The sine of one of the angles of a right triangle (often abbreviated sin) is the ratio of the length of the side of the triangle opposite the angle to the length of the triangle’s hypotenuse.
What is a tan in math?
Tangent, which is commonly abbreviated to three letters as T-A-N, is the ratio of the side opposite the angle we know, or want to know, over the side adjacent to that angle. The adjacent side is the one touching the angle that is NOT the hypotenuse, which is the side opposite the right angle.
