Recall that secant is one over cosine and tangent is sine over cosine, so your problem becomes:



Which is to say:



Multiply by



Check the unit circle, recalling that the sin value is the -coordinate



to see that:



But recall that you can go around the circle as many times as you like since you didn't provide a range for the answer and that once around is :



where
