What is csc sec and cot?
What is csc 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 .
Is Tan csc sec?
The functions are usually abbreviated: sine (sin), cosine (cos), tangent (tan) cosecant (csc), secant (sec), and cotangent (cot).
How do you remember sin Cos Tan csc sec cot?
An alternate way to remember the letters for Sin, Cos, and Tan is to memorize the nonsense syllables Oh, Ah, Oh-Ah (i.e. /oʊ ə ˈoʊ. ə/) for O/H, A/H, O/A. Or, to remember all six functions, Sin, Cos, Tan, Cot, Sec, and Csc, memorize the syllables O/H, A/H, Oh/Ah, Ah/Oh, H/A, H/O (i.e. /oʊ ə ˈoʊ.
What is csc in terms of sin?
The cosecant ( csc ) (\csc) (csc) The cosecant is the reciprocal of the sine. It is the ratio of the hypotenuse to the side opposite a given angle in a right triangle.
What is sec theta equal to?
The reciprocal cosine function is secant: sec(theta)=1/cos(theta). The reciprocal sine function is cosecant, csc(theta)=1/sin(theta).
How do you find cot 30 degrees?
The exact value of cot(30°) cot ( 30 ° ) is √3 .
Is CSC the inverse of sin?
Is cot the inverse of tan?
cot(x) = 1/tan(x) , so cotangent is basically the reciprocal of a tangent, or, in other words, the multiplicative inverse.
What does SOH CAH TOA mean?
“SOHCAHTOA” is a helpful mnemonic for remembering the definitions of the trigonometric functions sine, cosine, and tangent i.e., sine equals opposite over hypotenuse, cosine equals adjacent over hypotenuse, and tangent equals opposite over adjacent, (1) (2) (3) Other mnemonics include.

Is there a difference between arctan and cot?
No no. Cot (x)=1/tan (x) arctan (x)=tan -1 (x) ≠ 1/tan (x) Just to clarify, that notation doesn’t mean the multiplicative inverse in this context, but the inverse function.
Is tan inverse cot?
The Cotangent (cot) is the inverse of the tangent, i.e. at each point it takes the value that when added to the value of tan at that point would equal 0. In this case Tan is blue and Cot is red. Also useful to know: As you already know. Tan= Sin. Cos. and Cot is the inverse of Tan, therefore.
What is cosine times tangent?
The cosine (often abbreviated “cos”) is the ratio of the length of the side adjacent to the angle to the length of the hypotenuse. And the tangent (often abbreviated “tan”) is the ratio of the length of the side opposite the angle to the length of the side adjacent .
What is cot x equal to?
cotangent (cot) A trigonometric function of an angle equal to the reciprocal of its tangent, that is, cot x = 1/tan x. It is equal to the ratio of the length of the side adjacent to the angle to that of the opposite side in a right triangle.
