What are trigometric ratios?

Basically we have two. One is sine and the other is cosine Right from these two we can get tangent Reciprocal of sine is cosecant Reciprocal of cosine is secant Reciprocal of tangent is cotangent


What is the cos reciprocal?

The reciprocal of cosine is secant (short form: sec), which is the hypotenuse length divided by the adjacent length.


How do you acquire secant in scientific calculator?

You can calculate the cosine and then its reciprocal.


What is the reciprocal of a cosine?

1/cos(x)=sec(x). sec is short for secant.


How do you find the sec of a 38 degree angle?

Find the cosine of 38 degrees and then find its reciprocal.


When is secant not defined?

The secant of an angle is the reciprocal of the cosine of the angle. So the secant is not defined whenever the cosine is zero That is, whenever the angle is a multiple of 180 degrees (or pi radians).


How do you express complementary angles into a trigonometric function?

The sine of an angle is the cosine of its complement and conversely. The tan of an angle is the reciprocal of its complement.


Examples of operations of functions in trigonometry?

Trigonometry includes 12 baisic functions. Sine, Cosine, and Tangent are the three most baisic. Each of those functions has a reciprocal. Cosine's reciprocal is Secant, Sine reciprocal is Cosecant, and Tangent's reciprocal is Cotangent. Each of those six functions has an inverse funcion called Inverse Sine, Cos etc... or Arcsine, Arcosine, Arcsecant, etc.... The shorthand for each function is sin, caos, tan, sec, csc, cot. The inverses have a -1 notation like sin-1.


What is reciprocal in trigonometry?

The inverse of sine (sin) is cosecant (csc). The inverse of cosine (cos) is secant (sec). The inverse of tangent (tan) is cotangent (cot).


Why is the secant function is an even function and the tangent and cosecant are odd functions?

I find it convenient to express other trigonometric functions in terms of sine and cosine - that tends to simplify things. The secant function is even because it is the reciprocal of the cosine function, which is even. The tangent function is the sine divided by the cosine - an odd function divided by an even function. Therefore it is odd. The cosecant is the reciprocal of an odd function, so it is naturally also an odd function.


What is trigonometry of reciprocal relation?

cosecant = 1/sine secant = 1/cosine cotangent = 1/tangent


Is the inverse function of secant is the cosecant function?

No. The inverse of the secant is called the arc-secant. The relation between the secant and the cosecant is similar to the relation between the sine and the cosine - they are somehow related, but they are not inverse functions. The secant is the reciprocal of the cosine (sec x = 1 / cos x). The cosecant is the reciprocal of the sine (cos x = 1 / sin x).


What is cosine cubed?

It is cosine*cosine*cosine.


How are sine and cosine and secant related?

Sine and cosine are cofunctions, which means that their angles are complementary. Consequently, sin (90° - x) = cos x. Secant is the reciprocal of cosine so that sec x = 1/(cos x). Knowing these properties of trigonometric functions, among others, will really help you in other advance math courses.


How does the tangent function relate to sine and cosine?

Tangent = sine/cosine provided that cosine is non-zero. When cosine is 0, then tangent is undefined.


How do you find the angle of a cosine?

You mean, you have the cosine, and want the angle? That is called arc-cosine, often written as cos-1x. Your scientific calculator should have a "shift" key or something similar, which you press, followed by the cosine key. That will give you the inverse cosine or arc-cosine.


Why do cosine to the negative 1th power and cosine cancel out each other?

Cosine to the negative first power and cosine cancel each other out because cosine to the negative first power is one over cosine, and one over anything times anything is just one.
