This is from my first class at a math uni course and I have never studied how to do this in hs. I would appreciate any help with this :)

Suppose you knew what the sine is: Could you find the cosine?

This is not the easiest problem of its type. Can you show a simpler one that you were able to solve? Can you show how far you are able to get on this one?

And if they just gave you this one problem as review or to check your preparation, but you have never learned anything about this sort of problem, then you are misplaced, and probably need to move to the prerequisite course.

There was no simpler version of this type of question actually and the slides before this question were of how to find values of obtuse angles and no question was even similar to this one. Also this is my first day as a first year in uni and this is a mandatory first year math course and this course itself is a prerequisite. This isn’t a review question either btw, it’s a new thing

Then what you need to do is to fill in the prerequisite that you missed, on your own. (Unless possibly this is just a diagnostic test, and the material will be covered later. If I knew what the course is called, and what it covers, I'd have a better idea of where this problem might fit into it.)

What you need to learn depends on how much of trigonometry you missed, and how much is needed for the course. I'm assuming that you never learned anything like this, rather than that you simply think it looks harder than similar problems you did learn. So you'll need to figure out how far back to go in trig, and find a source that will take you through the part you need, at the right pace for you.

If you think you know enough to do this problem with help, we could go through it; but I'll need to see what you are able to do before trying to help. So I'll ask again, without the assumption that you were given such problems in this course: Is there a simpler version of this problem (e.g. with a sine instead of a cosecant, or with a different interval specified) that you could do?

Do you know the relationship between \(\displaystyle csc(\theta) \ \) and \(\displaystyle sin(\theta) \ \)? Please write it for us.

Do you know the relationship between \(\displaystyle cos(\theta) \ \) and \(\displaystyle sin(\theta) \ \)? Please write it for us.

How can you use the two relationships you wrote to solve the given problem?
