Evaluate for Theta Between 0 and 2pi, Secθ = -1

The video tutorial explains how to evaluate the angle Theta when the secant of Theta equals -1. It begins by discussing the relationship between secant and cosine, noting that secant is the reciprocal of the cosine function. The tutorial then guides viewers through finding the angle on the unit circle where the cosine equals -1, which corresponds to the angle π. The video concludes by emphasizing that the angle must be between 0 and 2π.
