operation of cosign in order to find what the degree measure would be if the co sin of X equals one half. So if you're using a T 84 or in 83 in order to punch this season, you would punch in your second and then you would punch in your coast on button and above the cosign button is where you're going to see that co sign. And it's not that negative one that just let me know we're doing the inverse because we have our cosign we just need to find with that degree is and then you're gonna type in one divided by two. So we're gonna pull up a similar one. So let's pull in. And now this one, we're not gonna press second, but we are going to do the inverse of cosign, and I have a parentheses that's already popping up. Since I don't have a square root or anything, I could just put one divided by two. And that tells me that my my ex, if co sin of X is one half, that means my ex is going to be 60 degrees
