Solve the equation for t. Give exact values. (Use the parameter k as necessary to represent any integer. Enter your answers as a comma-separated list. If there is no solution, enter NO SOLUTION.)

sec(t) = 2/sqrt3

t =

Solution

HERE Secant is negativ only in second and third quadrants

given Sec (t) =-2/sqrt3 in first quadrant sect = 2/sqrt3 when t=60 degrees

sect =-2/sqrt3 only when t=150,240 degrees i.e 90+60=150

   180+60=240
