Is csc inverse of sin?
We know that the cosecant is the reciprocal of the sine. Since sine is the ratio of the opposite to the hypotenuse, cosecant is the ratio of the hypotenuse to the opposite.
What is csc inverse equal to?
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°….
| csc-1 | cosec-1 |
|---|---|
| arccsc | arccosec |
| Arccsc | Arccosec |
Does sin 1 equal csc?
The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x .
What is sin inverse?
Sine inverse or arcsine is the inverse of sine function which returns the value of angle for which sine function is equal to opposite side and hypotenuse ratio. It generates the value of angle. But cosec function is the reciprocal of sine function and is not equal to sine inverse.
Is Arccsc the same as sin?
The functions are usually abbreviated: arcsine (arcsin), arccosine (arccos), arctangent (arctan) arccosecant (arccsc), arcsecant (arcsec), and arccotangent (arccot)….Math2.org Math Tables:
| sin(q) = opp/hyp | csc(q) = 1/sin(q) |
|---|---|
| tan(q) = sin(q)/cos(q) | cot(q) = 1/tan(q) |
What angle is sin 1 2?
Sines and cosines for special common angles
| Degrees | Radians | sine |
|---|---|---|
| 60° | π/3 | √3 / 2 |
| 45° | π/4 | √2 / 2 |
| 30° | π/6 | 1/2 |
| 0° | 0 | 0 |
What is sin 1 2 on the unit circle?
Using the unit circle, the angle with a sine of 12 in the first quadrant is π6 .
Is sin to the negative 1 csc?
On the other hand: csc(x)=(sin(x))−1=1sin(x) is the reciprocal of the sin 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 .
