In geometry, trigonometry is a branch of mathematics that deals with the sides and angles of a right-angled triangle.As you might have noticed, cosecant has a 'co' written in front of ''secant'.0 Using Degrees. Trigonometry Examples. Time Tables 14. Because the two sides have been shown to be equivalent, the equation is an identity. Cotangent is the reciprocal of tangent.1 2. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. Hence, we get the values for sine ratios,i. Three common trigonometric ratios are the sine (sin), cosine (cos), and tangent (tan). Trigonometric identities challenge problems. For instance, functions like sin^-1 (x) and cos^-1 (x) are inverse identities.

CBSE English Medium Class 10.2, 11 Find the derivative of the following functions: (iv) cosec x Let f (x) = cosec x f(x) = 1/sin𝑥 Let u = 1 & v = sin x ∴ f(x) = 𝑢/𝑣 So, f'(x) = (𝑢/𝑣)^′ Using quotient rule f'(x) = (𝑢^′ 𝑣 −〖 𝑣〗^′ 𝑢)/𝑣^2 Finding u' & v' u = 1 u' = 0 & v = sin x v' = cos x Now, f'(x) = (𝑢^′ 𝑣 −〖 𝑣〗^′ 𝑢)/𝑣^2
Conventionally, an abbreviation of each trigonometric function's name is used as its symbol in formulas. From the graphs of the secant and cosecant functions, we see that secant is an even function (like cosine) and cosecant is an odd function (like sine). Also, the period of secant and cosecant are the same as the period of cosine and sine, which is 2\pi 2π

Answer. We know that, sin A = opposite side / hypotenuse. Since cosecant function is positive in the first quadrant, thus cosec 60° value = 2/√3 or 1. The cosecant function is therefore odd. You can calculate value of csc() trignometric function easily using this tool. Tap for more steps Multiply −sin(x)sin(x) - sin ( x) sin ( x). Use the same approach to determine the derivatives of y = arccosx, y = arctanx, and y = arccotx. Note: Since, cosecant is an odd function, the value of cosec (-60°) = -cosec (60°).
Inverse Trigonometric Formulas: Trigonometry is a part of geometry, where we learn about the relationships between angles and sides of a right-angled triangle. Estimate each sum to the nearest hundred: (5130 + 1410) Q.
The sine and cosine of an acute angle are defined in the context of a right triangle: for the specified angle, its sine is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle (the hypotenuse ), and the cosine is the ratio of the length of the adjacent leg to that of the hypotenuse. Geometrically, these are identities involving certain functions of one or more angles. Sine, cosine, secant, and cosecant have period 2π while tangent and cotangent have period π. Cosec θ = 1/sin θ. Today, the most common versions of these abbreviations are "sin" for sine, "cos" for cosine, "tan" or "tg" for tangent, "sec" for secant, "csc" or "cosec" for cosecant, and "cot" or "ctg" for cotangent. We have certain trigonometric identities. It is used to find the angles with any trigonometric ratio. How do you find the value of CSC? csc(x) = (sin(x))⁻¹ . Pythagorean Identities.
There are different formulas in trigonometry depicting the relationships between trigonometric ratios and the angles for different quadrants. The Greeks focused on the calculation of chords, while mathematicians in India created the earliest
That is, sec(−x) = sec x sec ( − x) = sec x.
The cosecant function is the reciprocal of the sine function. All these trigonometric ratios are defined using the sides of the right triangle, such as an adjacent side, opposite side, and hypotenuse side.

cosec x = 1/sin x; sec x = 1/cos x; cot x = 1/tan x; Given below are the steps to create and remember a trigonometric table. cosine is the co-function of sine, which is why it is called that way (there's a 'co' written in front of 'sine'). Thus, we can say that the trigonometric ratios cosec and sin has a reciprocal relationship among them. What is secant and cosecant? Cosecant is the reciprocal of sine. Theorem 3. I think some of the blame for this confusion has to lie with the common convention of writing #sin^2(x)# to mean #sin(x)^2#.
The functions are usually abbreviated: sine (sin), cosine (cos), tangent (tan) cosecant (csc), secant (sec), and cotangent (cot). Syllabus

Ex 12. The reciprocal of the sine function is symmetrical about the x-axis. In the 1st quadrant, the sign of "Cosec" is positive. Step 1: Create a table with the top row listing the angles such as 0°, 30°, 45°, 60°, 90°, 180°, 270° and 360°and write all trigonometric functions in the first column such as sin, cos, tan, cosec, sec, cot. We know that sin x is 0 at integral multiples of π, hence the domain and range of cosecant are given by: Domain = R - nπ; Range = (-∞, -1] U [1, ∞) The range of cosecant can be derived exactly the same way how we derived for secant.
