Hi,

 

can you help me solve this? I know the first trigonometric function Ian sin2o + cos2O=1 but  how do i apply it to this? And how do I solve the other 2? 

 

Also, how do I use my calculator to find the angle for secO=3.02. I tried 1/-cos(3.02) and it gave me an error. What am i doing wrong?
