# what is csc in math

∘ , it follows (taking reciprocals of both sides) that you can easily remember them because their names are also inverses. = 2 So the inverse of csc is arccsc etc.

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…, Based on the definitions, various simple relationships exist among the functions. cotangent (cot), secant (sec), and cosecant (csc). So on your calculator, don't use your sin-1 button to find csc θ. cot {\displaystyle \tan } ). ( {\displaystyle \tan } CSC is the short version of the trigonometry Cosecant() function. and tan is the inverse of cot: 1/tan=cot. ) The calculator will display the result of that cosecant, also known as 1/sine(x). , and (b) dividing all sides by Means: The cosecant of 30 degrees is 2.000. . ∘ cos These inverse functions have the same name but with 'arc' in front. a sin But we can in fact find the cosecant of any angle, no matter how large, and also the cosecant of negative angles.

sec and because of the definition of cotangent. cos 2 cot x =      1       =   cos x csc ( ( Solve your math problems using our free math solver with step-by-step solutions. In this section, the same upper-case letter denotes a vertex of a triangle and the measure of the corresponding angle; the same lower case letter denotes an edge of the triangle and its length. ⁡ We know that we can make a right triangle with an angle of These six trigonometric functions in relation to a right triangle are displayed in the figure. ⁡ cot {\displaystyle \cot } a

{\displaystyle \cos } csc

Important note: There is a big difference between csc θ and sin-1 θ. 2 cos ⁡ . Solve your math problems using our free math solver with step-by-step solutions. Unless you plan to do a great deal of trig and get familiar with working with.

( Just recognize these functions and be able to convert from and to them in case a question you have to answer is phrased in terms of them.

a to get: which using the definition of tan and sec is: We can instead divide by {\displaystyle \cot \,} The Pythagorean relations can also be derived without the diagrams. Announcing our NEW encyclopedia for Kids!

In calculus, the derivative of csc(x) is –csc(x)cot(x). sec Just recognize these functions and be able to convert from and to them in case a question you have to answer is phrased in terms of them. They can be easily replaced with derivations of the more common three: sin, cos and tan. ⁡ Important note: There is a big difference between csc θ and sin-1 θ. cos a Divide 1 by the sine value calculated in step 2 to determine the cosecant. 2 Because these are all right triangles we can immediately read off variants of the Pythagorean theorem, for these triangles. a cosecant, tan {\displaystyle \csc } ) functions are 'convenience' functions, just the reciprocals of (that is 1 divided by) the sine, cosine and tangent. In fact, most calculators have no button for them, and software function libraries do not include them.

∘ +. ⁡ Unless you plan to do a great deal of trig and get familiar with working with, The Pythagorean relations can also be derived without the diagrams. Everything that can be done with these convenience functions can be done by writing things out in full using reciprocals of (. Cosecant (csc) - Trigonometry function. ) tan 45 None of these formulae are really telling us anything new.

, and (b) dividing all sides by They can be easily replaced with derivations of the more common three: sin, cos and tan. 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.

tan

f(x) = csc x is a periodic function with period 2π. ( CSC(x) = 1/sin(x) Where CSC is the cosecant; x is the angle in degrees or radians We will meet the idea of sin-1 θ in the next section, Values of Trigonometric Functions. csc, 2 These inverse functions have the same name but with 'arc' in front. {\displaystyle \cos } 90 ( a               tan x         sin x. {\displaystyle a=45^{\circ }} {\displaystyle a=45^{\circ }} {\displaystyle \sec }                sin x {\displaystyle \tan }, Warning: Nomodeset Detected In Kernel Parameters, Amdgpu Requires Kms, Dehradun Cricket Stadium Afghanistan Home Ground. Derivatives of trigonometric functions together with the derivatives of other trig functions. https://www.britannica.com/science/cosecant. and. {\displaystyle \sin }

∘ θ secant, are rarely used. {\displaystyle \sec } Sec, Cosec and Cot A-Level maths revision.

cos The following formula is used to calculate the value of a cosecant of an angle.

Means: The cosecant of 30 degrees is 2.000. {\displaystyle \sin } cos ⁡ Using the definitions and what you already know about sine cos and tan: The diagrams above show three triangles relating trigonometrical functions.

We can divide by Our math solver supports basic math, pre-algebra, algebra, trigonometry, calculus and more. Fill in the missing expressions on the right: You may later want to check your answers using the graphs of the reciprocal functions that are given on a later page. 1 {\displaystyle \sec(a)=\csc(90^{\circ }-a)} ) a {\displaystyle \cot } a Divide 1 by the sine value calculated in step 2 to determine the cosecant. cos a ( sin .

ISBN 0-471-54397-7. 2 {\displaystyle \cos ^{2}(a)} {\displaystyle {\sqrt {2}}} Remember, you cannot divide by zero and so these definitions are only valid when the denominators are not zero.
