[0, 2π].
Verify your solutions by graphing on a graphing calculator. (Enter your answers as a comma-separated list. Round your answers to four decimal places.)
[1 − sin^2(x)][sec(x)] = −0.3
Answer by oscargut(2103) About Me  (Show Source):
You can put this solution on YOUR website!
[1 − sin^2(x)][sec(x)] = -0.3
cos^2(x)/cos(x) = -0.3
cos(x) = -0.3
Then solve that equation
