Depends on what type of calculator you are using. I have a Ti-86. There is a button that says “solver”. To get to mine, I have to hit the 2nd key first and then the graph button.
csc is just an inverse of cos so you can use the cos^-1 button (right above cos on the ti)
The answer to the 4sinx question is 0.3172805.
