## What is the value of SEC square 180 degree?

The value of sec 180 degrees can be calculated by constructing an angle of 180° with the x-axis, and then finding the coordinates of the corresponding point (-1, 0) on the unit circle. The value of sec 180° is equal to the reciprocal of the x-coordinate(-1). ∴ sec 180° = -1.

**IS 180 is equal to pie?**

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. One degree is pi over 180 and if you want a decimal value for this you can use your calculator pi divided by 180, this is approximately . 0175.

**What is the value of tan 180 A?**

0

The value of tan 180 degrees is 0, i.e. tan 180° = 0.

#### Why do you multiply by pi 180?

why can you convert from radians to degrees by multiplying by 180/pi and from degrees to radians by multiplying by pi/180? Because say you have 2pi radians, and as we remember pi=180 degrees, so 2pi = 2(180). 2pi = 2pi/1 so to get rid of the pi in the numerator, we put pi in the denominator.

**How do you solve tan 180?**

Tan 180 Degrees Using Unit Circle To find the value of tan 180 degrees using the unit circle: Rotate ‘r’ anticlockwise to form 180° angle with the positive x-axis. The tan of 180 degrees equals the y-coordinate(0) divided by x-coordinate(-1) of the point of intersection (-1, 0) of unit circle and r.

**How do you find the value of cos180?**

The value of cos 180 degrees can be calculated by constructing an angle of 180° with the x-axis, and then finding the coordinates of the corresponding point (-1, 0) on the unit circle. The value of cos 180° is equal to the x-coordinate (-1). ∴ cos 180° = -1.
