The reciprocal sine function is cosecant, csc(theta)=1/sin(theta).
What are the 3 reciprocal identities?
Their names are cosecant, secant and cotangent. Cosecant is the reciprocal identity of sine, secant that of cosine and cotangent that of tangent.
What is opposite of sine?
Arcsine is the inverse of sine function. It is used to evaluate the angle whose sine value is equal to the ratio of its opposite side and hypotenuse. Therefore, if we know the length of opposite side and hypotenuse, then we can find the measure of angle.
What are the 6 reciprocal identities?

What is sin30 value?
The value of sin 30 degrees is 0.5. Sin 30 is also written as sin π/6, in radians.
What is the reciprocal function of sine apex?
Cosecant is the reciprocal of sine. Its abbreviation is csc. To determine csc, just flip sin over.
What is a reciprocal of 10?
The reciprocal of 10 is 0.1.
What is a sin in math?
In trigonometry, the sine function can be defined as the ratio of the length of the opposite side to that of the hypotenuse in a right-angled triangle. The sine function is used to find the unknown angle or sides of a right triangle.
What is a reciprocal trig function?
Reciprocal Identities are the reciprocals of the six main trigonometric functions, namely sine, cosine, tangent, cotangent, secant, cosecant. The important thing to note is that reciprocal identities are not the same as the inverse trigonometric functions.
Is the inverse of sin csc?
The reciprocal is found by turning the fraction upside down. So the reciprocal of the sine function is called the cosecant and is equal to the hypotenuse / opposite.
What are the 6 trig ratios?
There are six functions of an angle commonly used in trigonometry. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).
What does arcsec mean?
An arcsecond (denoted by the symbol “) is an anglular measurement equal to 1/3600 of a degree or 1/60 of an arcminute. There are also 206,264.5” in a radian, so that 1” = 4.848 ×10-6 radians.
Is cosecant sine over cosine?
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 .
Is Arcsecant just cosine?
So arccos is defined precisely this way: fixing one interval where cos is one-one, you define arccos in that interval by the property that arccosx is the number y such that cosy=x, in other words, it returns you the value of angle whose cosine is x.
