What is the ratio that is the reciprocal of the cosine?
it would be secant, 1/cosine
What is the reciprocal of a cosine?
1/cos(x)=sec(x). sec is short for secant.
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 the cosine of -90?
Cosine of -90 is 0.
How do you get a reciprocal?
a reciprocal is just the number flipped over the reciprocal of 3 is 1/3 the reciprocal of 4/3 is 3/4
What is Secant the reciprocal of?
Cosine.
What is the ratio that is the reciprocal of the cosine?
it would be secant, 1/cosine
How do you acquire secant in scientific calculator?
You can calculate the cosine and then its reciprocal.
What is the cos reciprocal?
The reciprocal of cosine is secant (short form: sec), which is the hypotenuse length divided by the adjacent length.
What is the reciprocal of a cosine?
1/cos(x)=sec(x). sec is short for secant.
What is a reciprocal trig function?
A reciprocal trigonometric function is the ratio of the reciprocal of a trigonometric function to either the sine, cosine, or tangent function. The reciprocal of the sine function is the cosecant function, the reciprocal of the cosine function is the secant function, and the reciprocal of the tangent function is the cotangent function. These functions are useful in solving trigonometric equations and graphing trigonometric functions.
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).
What is trigonometry of reciprocal relation?
cosecant = 1/sine secant = 1/cosine cotangent = 1/tangent
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.
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.
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.
