What is the exact value of sec 180?
What is the exact value of sec 180?
-1
The exact value of sec 180 degrees is -1.
Why is π equal to 180?
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.

Is pi 3.14 or 180?
π radians is approximately 3.14 radians. So, just approximating the constant π as 3.14 gives you the same kind of thing; a number of radians, as an angle measure. On the other hand, it’s completely accurate to say that π radians =180∘.
How many pi is 180 degrees?
3.14 Rad
Hence, from the above equation, we can say, 180 degrees is equal to π radian….Degrees to Radians Chart.
| Angle in Degrees | Angle in Radians |

What is the value of SEC?
The secant of angle zero degrees is written as in Sexagesimal system and the exact value of secant of angle zero degrees is equal to one.
What is Cotpi?
Cot pi is the value of cotangent trigonometric function for an angle equal to π radians. The value of cot pi is not defined.
What is the value of Tanπ 2?
Note: Since, tangent is an odd function, the value of tan(-pi/2) = -tan(pi/2) = undefined.
What’s secant equal to?
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 .
