What is the formula for CSC?
For example, csc A = 1/sin A, sec A = 1/cos A, cot A = 1/tan A, and tan A = sin A/cos A.
What is the csc in math?
moreIn 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. The abbreviation is csc. csc θ = hypotenuse / opposite.
Is cosecant the inverse of sine?
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.
How do you find cosecant on the unit circle?
The cosecant function is the reciprocal of the sine function (cscx=1sinx) x = 1 sin . It can be found for an angle t by using the y -coordinate of the associated point on the unit circle: csct=1y t = 1 y . The cotangent function is the reciprocal of the tangent function (cotx=1tanx=costsint) x = 1 tan .
What is derivative of Cscx?
What is Derivative of Cosec x? The differentiation of cosec x with respect to angle x is written as d(cosec x)/dx = (cosec x)’ = -cot x cosec x. Derivative of cosec x can be calculated using the derivative of sin x.
What is the inverse of csc?
The inverse function of cosecant. Basic idea: In order to find csc–1 2, we ask “what angle has cosecant equal to 2?” The answer is 30°. As a result we say csc–1 2 = 30°. In radians this is csc–1 2 = π/6.

How do you do Tanh on a TI 30xs?
Press [2nd] [HYP] to access the hyperbolic function (sinh, cosh, tanh) of the trig function to be used.
How do I know if I have SOH CAH TOA?
In this geometry lesson, you’re going to learn all about SohCahToa. It’s probably one of the most famous math mnemonics alongside PEMDAS.
It’s defined as:
- SOH: Sin(θ) = Opposite / Hypotenuse.
- CAH: Cos(θ) = Adjacent / Hypotenuse.
- TOA: Tan(θ) = Opposite / Adjacent.
How do I change my TI-30X IIS to radians?
How do I convert a number between Degrees and Radians on the TI-30X IIB or TI-30X IIS?

What function is the reciprocal of the cosecant function?
sine function
Each trigonometric function is a reciprocal of another trigonometric function. The sine function is the reciprocal of the cosecant function and vice-versa; the cosine function is the reciprocal of the secant function and vice-versa; cotangent function is the reciprocal of the tangent function and vice-versa.
How do you find the cosecant of theta?
The reciprocal sine function is cosecant, csc(theta)=1/sin(theta). The reciprocal tangent function is cotangent, expressed two ways: cot(theta)=1/tan(theta) or cot(theta)=cos(theta)/sin(theta).
How do you do cosecant on a TI 83 Plus?
Find sec, csc, and cot by calculator. To find sec x, first find value of cos x, then press 1/x. To find csc x, first find value of sin x, then press 1/x.
What does csc graph look like?
The cosecant goes down to the top of the sine curve and up to the bottom of the sine curve. After using the asymptotes and reciprocal as guides to sketch the cosecant curve, you can erase those extra lines, leaving just y = csc x. The figure that follows shows what this function looks like all on its own.
Is cosecant the inverse of cosine?
Cosecant is the reciprocal of sine. Secant is the reciprocal of cosine. Cotangent is the reciprocal of tangent. When solving right triangles the three main identities are traditionally used.
What is secant formula?
The length of the hypotenuse, when divided by the length of the adjacent side, will give the secant of the angle in a right triangle. Therefore, its basic formula is: sec X = frac{Hypotenuse}{Adjacent Side} Also, it is the reciprocal of the cosine value.
