The calculator does not have built-in secant, cosecant, or cotangent functions. You must calculate these functions by using the appropriate reciprocal identities. To find the inverse of a secant, cosecant, or cotangent function, use the reciprocal identity’s inverse with the reciprocal of the input.
How do you do Sec 2 on a scientific calculator?
For the “2” part of sec2θ, most calculators that have an x2 key require you to compute cosθ first, and then use the x2 key.
How do you get 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 does Sec 2 theta equal?

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. It is not commonly used, and is equal to 1/cosine.
Is secant the inverse of cosine?
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 sec formula?
Therefore, its basic formula is: sec X = \frac{Hypotenuse}{Adjacent Side} Also, it is the reciprocal of the cosine value.
What is secant in trigonometry?
Secant Calculator In trigonometry, secant is the ratio of hypotenuse to the shorter side adjacent to an acute angle in a right angled triangle. Secant function is reciprocal of cosine function. Find the secant of an angle using the below online Secant Calculator.
What is sec X calculator?
This Sec x calculator provides the corresponding values of the angles in secant radians and secant degrees. Sec x always goes to infinity when cosine function is zero, since they both are inverted functions. Just copy and paste the below code to your webpage where you want to display this calculator.
What is the inverse secant of SEC?
Sec x Calculation: In geometrical terms, a secant is defined as a straight line that intersects a curve at two or more points. In trigonometry, the inverse secant function is also known as arcsec (sec-1). Therefore, the value of sec and arcsec will be inverted.
What is secsecant function?
Secant function is reciprocal of cosine function. Find the secant of an angle using the below online Secant Calculator. This Sec x calculator provides the corresponding values of the angles in secant radians and secant degrees.
