## What are the trigonometric functions of pi?

The 6 trigonometric values of π3 are:

- sin(π3)=√32.
- cos(π3)=12.
- tan(π3)=√3.
- csc(π3)=2√33.
- sec(π3)=2.
- cot(π3)=√33.

### What are the six trigonometric functions of negative pi?

1 Answer

- cos(−π6)=√32.
- sin(−π6)=−12.
- tan(−π6)=−1√3.
- sec(−π6)=2√3.
- cot(−π6)=−√3.

#### What is the value of sin 2 pi by 3?

Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. The exact value of sin(π3) sin ( π 3 ) is √32 .

**Why is 180 degrees equal to pi radians?**

We’re talking about radian measure of angles. One degree in radians, always remember that 180 degree equals pi. 180 degrees equals pi radians, so to get one degree divide both sides by 180.

**What is degrees in terms of pi?**

Pi radians are equal to 180 degrees: π rad = 180°

## What is value of sin pi?

0

What is the value of sin pi? 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 are the six trig function values of Pi / 3?

The 6 trigonometric values of π 3 are: sin(π 3) = √3 2 cos(π 3) = 1 2 tan(π 3) = √3

#### Is the unit circle useful in a trig class?

One of the problems with most trig classes is that they tend to concentrate on right triangle trig and do everything in terms of degrees. Then you get to a calculus course where almost everything is done in radians and the unit circle is a very useful tool.

**What are the problems with right triangle trig?**

If your device is not in landscape mode many of the equations will run off the side of your device (should be able to scroll to see them) and some of the menu items will be cut off due to the narrow screen width. One of the problems with most trig classes is that they tend to concentrate on right triangle trig and do everything in terms of degrees.
