## What is Sinπ?

In trigonometry, we use pi (π) for 180 degrees to represent the angle in radians.

Hence, sin π is equal to sin 180 or sin π = 0..

## What does sin 2x equal?

1. sin(2x)=2sin(x)cos(x).

## How is sin calculated?

In a right triangle, the sine of an angle is the length of the opposite side divided by the length of the hypotenuse. Try this Drag any vertex of the triangle and see how the sine of A and C are calculated. The sine function, along with cosine and tangent, is one of the three most common trigonometric functions.

## What is 1 sin called?

Other Names. Sometimes sin-1 is called asin or arcsin. Likewise cos-1 is called acos or arccos. And tan-1 is called atan or arctan.

## What is sine to the negative 1?

The Value of the Inverse Sin of 1 As you can see below, the inverse sin-1 (1) is 90° or, in radian measure, Π/2 . ‘1’ represents the maximum value of the sine function . It happens at Π/2 and then again at 3Π/2 etc..

## Is cot the inverse of tan?

cot(x) = 1/tan(x) , so cotangent is basically the reciprocal of a tangent, or, in other words, the multiplicative inverse. arctan(x) is the angle whose tangent is x.

## Is sin 1x the same as Sinx 1?

The notation sin-1(x) has been misunderstood to mean 1/sin(x). … So sin-1(x) means the inverse sine of x, that is, the function that undoes the sine function. It is not equal to 1/sin(x).

## Does cot Tan 1?

Inverse Properties tan(tan -1(x)) = x for any x. cot -1(cot(x)) = x for x in the interval (0 , ). cot(cot -1(x)) = x for any x. Because of the intervals chosen we get this identity, similar to the one stated for inverse sine and cosine.

## Are Sin 1 and CSC the same?

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 the sine inverse of 0?

## What is the value of sin 1 1?

The inverse sin of 1, i.e., sin-1 (1) is a very unique value for the inverse sine function. Sin-1(x) will give us the angle whose sine is x. Hence, sin-1 (1) is equal to the angle whose sine is 1. Since the inverse sin-1 (1) is 90° or Π/2.

## What does CSC stand for?

## What are the 9 trig identities?

Sine, Cosine and TangentSine Function:sin(θ) = Opposite / HypotenuseCosine Function:cos(θ) = Adjacent / HypotenuseTangent Function:tan(θ) = Opposite / Adjacent

## What is Arctan 1 in terms of pi?

The only values of θ that make the equation tanθ=1 true are π4 and 5π4 . … Thus, arctan1=π4 .

## What is CSC in terms of sin?

cosecant. The cosecant is the reciprocal of the sine. csc ( A ) = 1 sin ( A ) \csc(A)=\dfrac{1}{\sin(A)} csc(A)=sin(A)1. secant. The secant is the reciprocal of the cosine.

## Does Arcsin cancel out sin?

The arcsine function is the inverse function for the sine function on the interval [ − π / 2 , π / 2 ] . So they “cancel” each other under composition of functions, as follows.

## What is the inverse of tan?

arctan functionThe arctan function is the inverse of the tangent function. It returns the angle whose tangent is a given number. Try this Drag any vertex of the triangle and see how the angle C is calculated using the arctan() function. Means: The angle whose tangent is 0.577 is 30 degrees.

## Does Arcsin sin 1?

Strictly speaking, the symbol sin-1( ) or Arcsin( ) is used for the Arcsine function, the function that undoes the sine. … Arcsine may be thought of as “the angle whose sine is” making arcsine(1/2) mean “the angle whose sine is 1/2” or /6.
