Is csc the same as cos -1
WebNo, because cos⁻¹ x is NOT the same as (cos x)⁻¹. Therefore, arccos x is NOT 1/cos x. To be precise, arccos x = 𝑖 ln [ x - 𝑖√(1-x²) ] The ⁻¹ beside the name of a function refers to the inverse function, not the reciprocal. So, this notion is NOT an exponent. This inconsistency in notation often causes confusion with students. WebWork with one side of the equation at a time, start with the most complicated *Note* Often you will only need to work with one side only Example 1: Prove the Identity Solution 1: Start with the more complicated side and see if you can get it to be the same as the right side csc 2 𝜃 − 1 csc 2 𝜃 = cos 2 𝜃 cot 2 𝜃 csc 2 𝜃 = cos 2 ...

WebCosecant (x) is equal to 1/sin (x) and the domain is any real number. So cosecant (45 degrees) is 2/sqrt (2) whereas sin (45 degrees) sqrt (2)/2 Arcsin (x) is equal to the angle y such that sin (y)=x and the domain is -1 to +1. So arcsin (0) is equal to 0 degrees, 180 degrees, etc. Arcsin (-1) is equal to -90 degrees, 270 degrees, etc. WebHowever, the trig function csc stands for cosecant which is completely different from cosine. As you might have noticed, cosecant has a 'co' written in front of ''secant'. So we can see here that cosecant is the co-function of secant. Similarly, cotangent is the co …
WebSome of the most commonly used trigonometric identities are derived from the Pythagorean Theorem , like the following: sin2(x) + cos2(x) = 1 1 + tan2(x) = sec2(x) 1 + cot2(x) = csc2(x) There are also the reciprocal identities : sin(x) = 1 csc ( x) cos(x) = 1 sec ( x) tan(x) = 1 cot ( x) csc(x) = 1 sin ( x) sec(x) = 1 cos ( x) cot(x) = 1 tanx WebIn a right triangle, the cosecant of an angle is the length of the hypotenuse divided by the length of the opposite side. In a formula, it is abbreviated to just 'csc'. Of the six possible …
WebAs explained above, cos x is positive in the first quadrant (only first quadrant to be considered) and negative in the second quadrant of the common interval [-π /2, π] . These two quadrant are covered in by the interval [0, π] So, the range of y = cos-1 (x) is [0, π] More clearly, the range of y = cos-1 (x) is. 0 ≤ y ≤ π WebNov 26, 2012 · To do so, we multiply the first term by: (1+cosx)/ (1+cosx), and the second term by: (1-cosx)/ (1-cosx). Notice that (1+cosx)/ (1+cosx) = 1 and that (1-cosx)/ (1-cosx) = 1, so you are not actually altering the value of the terms you are multiplying them by. [1/ (1-cosx) * (1+cosx)/ (1+cosx)] + [1/ (1+cosx) * (1-cosx)/ (1-cosx)]
WebCsc-1, CSC-1, csc-1, or csc −1 may refer to: . csc x−1 = csc(x)−1 = excsc(x) or excosecant of x, an old trigonometric function; csc −1 y = csc −1 (y), sometimes interpreted as arccsc(y) …

What I don't understand is why csc ( α) = 1 sin ( α) and sec ( α) = 1 cos ( α) Wouldn't it be easier to let the "co"-secant refer to the multiplicative inverse of the "co"-sine function?

I think some of the blame for this confusion has to lie with the common convention of writing sin2(x) to mean sin(x)2. So when you have csc(x) = 1 sin(x) = sin(x)−1 you might think that we would also write that as sin−1(x), but that's reserved for arcsin(x). Answer link boston organics offer codeWebThe notation cos − 1 ( x) means the same thing as arccos ( x). If you wanted to talk about sec ( x), which is 1 / cos ( x), you would write ( cos ( x)) − 1.
