Question

Use a calculator to find all solutions in the interval (0, 2π). Round the answers to two decimal places. (Enter your answers as a comma-separated list. If there is no solution, enter NO SOLUTION.)
sec t = 9.44
  Hint: The equation is equivalent to 
cos t = 1/(9.44).

anonymous · Answer

sec t = 9.44
1/cos t = 9.44
cos t = 1/9.44
t=arccos (1/9.44)
Basic angle of t = 83.92 degrees.

First quadrants and fourth quadrants , cos theta = +ve.

t= 83.92, No solution for 2nd quadrants , No solution for 3rd quadrants , 360-83.92
t=83.92, 276.08
