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 .
Secant is the reciprocal of cosine. Its abbreviation is sec. To determine sec, just flip cos over. Cotangent is the reciprocal of tangent.
The secant formula helps in finding out the hypotenuse, the length, and the adjacent side of a right-angled triangle. The formula is sec θ = H/B.
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.
Based on the definitions, various simple relationships exist among the functions. For example, csc A = 1/sin A, sec A = 1/cos A, cot A = 1/tan A, and tan A = sin A/cos A.
In a right angled triangle, the cosecant of an angle is: The length of the hypotenuse divided by the length of the side opposite the angle. The abbreviation is csc. csc θ = hypotenuse / opposite.
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.
The cosecant is the reciprocal of the sine. The secant is the reciprocal of the cosine. The cotangent is the reciprocal of the tangent.
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.
And then just do 1. Over the sine of PI over 3. And this would give me the cosecant of PI over 3. IfMoreAnd then just do 1. Over the sine of PI over 3. And this would give me the cosecant of PI over 3. If I wanted to find the cotangent of PI over 3 what I could do is make another fraction.
So for example if I wanted the cosecant of 70 degrees now anytime that you're using your sine cosineMoreSo for example if I wanted the cosecant of 70 degrees now anytime that you're using your sine cosine and tangent buttons in your calculator. You need to make sure that you check your mode.
