Important note: There is a big difference between csc θ and sin-1 θ. I am going to say that you understand what sine is. sec x = 1 cos x Range equals [-1,1]. Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor. The derivative of $\cot x$ is equal to $-\csc^{2}x \ dx$, that means that the integral of $\csc^{2}x\ dx$ is $-\cot x$, so our final end result of $\csc^{2}x \ dx$ will be: $$-\cot x$$ Thank you for being at this moment with us:) Leave a Reply Cancel reply. The following diagram shows the Reciprocal Trigonometric Functions. The secant function is the reciprocal of the cosine function. cotangent, and sin ⁡ θ = sin ⁡ ( θ + 2 k π ) {\displaystyle \sin \theta =\sin \left (\theta +2k\pi \right)\quad } and. First note that two functions are equivalent if * They have the exact same domain. We will meet the idea of sin-1 θ in the next section, Values of Trigonometric Functions. cosecant csc cosec. The abbreviation of secant is sec. Definition: The tangent of , denoted is. The abbreviation of cosecant is csc or cosec. In a right angled triangle, the cosecant of an angle is: The length of the hypotenuse divided by the length of the side opposite the angle. Cosecant is the reciprocal of sine and not the reciprocal of cosine. When solving right triangles the three main identities are traditionally used. Cosecant definition is - a trigonometric function that for an acute angle is the ratio between the hypotenuse of a right triangle of which the angle is considered part and the leg opposite the angle. The reciprocal is found by turning the fraction upside down. These inverse functions have the same name but with 'arc' in front. Secant is the reciprocal of cosine. Copyright © 2014 by Houghton Mifflin Harcourt Publishing Company. This means that at any value of x, the rate of change or slope of csc(x) is –csc(x)cot(x). If this is the question, then the misunderstanding is quite fundamental and you deserve a perfectly straightforward answer. The cosecant squared trigonometric rule is mainly used as a formula in two cases. The trig function cosecant, written csc θ. csc θ equals .For acute angles, csc θ can be found by the SOHCAHTOA definition, shown below on the left. The abbreviation is cot cot (θ) = adjacent / opposite They can be easily replaced with derivations of the more common three: sin, cos and tan. Means: The cosecant of 30 degrees is 2.000. So the reciprocal of the sine function is called the cosecant and is equal to the hypotenuse / opposite. Always, always, the sine of an angle is equal to the opposite side divided by the hypotenuse (opp/hyp in the diagram). Next, add this reference angle to π π to find the solution in the third quadrant. Take the inverse cosecant of both sides of the equation to extract from inside the cosecant. 0. #csc x=1/sin x# If you try to calculate this for angle #0# you will get an expression with dividing by zero which cannot be calculated, so you cannot calculate cosecans of an angle which is a solution of #sinx=0#, so the cosecans function is undefined for … For more on this see To see the answer, pass your mouse over the colored area. Of the six possible trigonometric functions, For example, the triangle contains an angle A, and the ratio of the side opposite to A and the side opposite to the right angle (the hypotenuse) is… 0. Secant, cosecant and cotangent, almost always written as sec, cosec and cot are trigonometric functions like sin, cos and tan. This question was given to me exactly the same way I have written it here, they didn't ask for anything else but the value. As you can see from the equation above, the cosecant is equal to 1 divided by the sin of the same angle. It is the reciprocal (or multiplicative inverse) of the sine. When we see "arccsc A", we interpret it as "the angle whose cosecant is A". 1. Other articles where Cosecant is discussed: trigonometry: cotangent (cot), secant (sec), and cosecant (csc). To cover the answer again, click "Refresh" ("Reload"). Cosecant Calculator. Cosecant is the reciprocal of sine.

A function of a number x, equal to the cosecant of an angle whose measure in radians is equal to x. is, Definition: The cosecant of , denoted What does cosecant mean? (See Interior angles of a triangle). Thus the values of x at which csc x is undefined are Other articles where Cosecant is discussed: trigonometry: cotangent (cot), secant (sec), and cosecant (csc). See http://en.m.wikipedia.org/wiki/Cosecant#Reciprocal_functions The cotangent function is the reciprocal of the tangent function. General. 3 Cosecant, Secant, & Cotangent < Back | Next > In many cases we will want to know the reciprocal ratios of trigonometric functions. For more on this see Functions of large and negative angles. In a formula, it is abbreviated to just 'csc'. Because the cosecant function is the reciprocal of the sine function, it goes to infinity whenever the sine function is zero. What is $\csc^{-1}x$ = equal to? In a right triangle, the two variable angles are always less than 90° we can derive two more identities by Evaluate. Cosecant Definition A cosecant is defined as the inverse value of the sine of a value. These six trigonometric functions in relation to a right triangle are displayed in the figure. 0 (trigonometry) In a right triangle, the reciprocal of the sine of an angle. functions: Using the alternate definition of sine and cosine as ratios CSC 520° is equal to. The cosecant function is positive in the first and second quadrants. To avoid confusion I will refer to the inverse sine function as [math]\arcsin[/math] . The second one involves finding an angle whose sine is θ. See more. cant. The cotangent function is the reciprocal of the tangent function.
