Use periodicity to first rewrite each expression as the same trigonometric function of an angle in [-T, π). Then use that angle to determine the exact value from the unit circle. If undefined, write DNE. sec(-25) = sec( csc (¹7) = csc ( sin(- 17 ) = sin([])=[ sec (³) = sec ( Use periodicity to first rewrite each expression as the same trigonometric function of an angle in [0, π).
