What are the values of all the trigonometric functions at 270 degrees?

At 270 degrees, which is equivalent to
3π/2 radians, we can determine the values of the six primary trigonometric functions: sine, cosine, tangent, cosecant, secant, and cotangent.

1. Sine Function

The sine of 270 degrees is given by:
sin(270°) = -1

2. Cosine Function

The cosine of 270 degrees is:
cos(270°) = 0

3. Tangent Function

tan(270°) = sin(270°) / cos(270°) = -1 / 0
Therefore, tangent is undefined at this angle.

4. Cosecant Function

The cosecant is the reciprocal of sine:
csc(270°) = 1 / sin(270°) = 1 / -1 = -1

5. Secant Function

The secant is the reciprocal of cosine:
sec(270°) = 1 / cos(270°) = 1 / 0
Consequently, secant is also undefined at this angle.

6. Cotangent Function

The cotangent is the reciprocal of tangent:
cot(270°) = 1 / tan(270°)
Given that tangent is undefined, cotangent is also undefined at 270 degrees.

In summary, the values for trigonometric functions at 270 degrees are as follows:

  • sin(270°) = -1
  • cos(270°) = 0
  • tan(270°) = undefined
  • csc(270°) = -1
  • sec(270°) = undefined
  • cot(270°) = undefined

Understanding these values can help in various applications of trigonometry, such as solving equations or analyzing wave behavior.
