WebMu Alpha Theta National Convention: Hawaii, 2005 Solutions – Poi Bowl – Mu Division 1. B. You can guess and check by cubing each of the given possibilities. Or it's easy to do in polar coordinates: you need a magnitude of 1 so r = 1, and a theta such that 3*theta = 0, so theta = 0 or theta = pi/3 or theta = 2pi/3 (or Npi/3 for any integer N). So the cube root of 1 is r = 1, … WebThe cosecant function is therefore odd. Finally, the secant function is the reciprocal of the cosine function, and the secant of a negative angle is interpreted as sec(−θ) = 1 cos(−θ) = 1 cosθ = secθ sec ( − θ) = 1 cos ( − θ) = 1 cos θ = sec θ. The secant function is therefore even.
