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?

Step 1

In order to find the angle θ, we need to convert sec θ in cos θ.

Step 2

We have sec θ=3.02. Let us convert it in terms of cos θ.

**Or you can type arcsec(3.02) in calculator and set the angle in degrees.**

Step 3

Now, we need to apply inverse...
