The secant function is defined as the reciprocal of the cosine function. To find sec(π/2), we first need to determine the value of cos(π/2).
Value of Cosine at π/2
At the angle π/2 radians (or 90 degrees), the cosine value is:
- cos(π/2) = 0
Calculating Secant
Since sec(θ) = 1/cos(θ), we can substitute the value we found:
- sec(π/2) = 1/cos(π/2) = 1/0
Conclusion on Sec(π/2)
Since division by zero is undefined, we conclude that:
sec(π/2) is undefined.
