How do you find sec and cot?

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 .

### How do you find SEC CSC and cot?

tan x = sin x cos x . 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 .

### What is the formula for secant?

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 .

What’s secant equal to?

The secant is the reciprocal of the cosine. It is the ratio of the hypotenuse to the side adjacent to a given angle in a right triangle.

## What is the value of sec?

The value of Sec 180 degrees is -1. Sec 180 degrees in radians is written as sec (180° × π/180°), i.e., sec (π) or sec (3.141592. . .).

## Does the TI-84 Plus C Silver Edition have secant and cosecant functions?

The TI-84 Plus C Silver Edition does not have built-in secant, cosecant and cotangent trigonometric functions. To compute these trigonometric functions, use the properties of trigonometric functions which are listed below. Example: Solve for the cosecant of 31.67 degrees.

What symbols does the TI-89 graphing calculator have?
