Best ResponseYou've already chosen the best response.0I suppose this is meant ironically. But I will forgive your misguidedness. Asking others for a solution to a specific problem will not bring you far. There will not always be someone competent there to help you. The basics in every science and especially math is looking things up in the literature, furthermore as these topics are so common.

Best ResponseYou've already chosen the best response.0Yes, only not for letting others solve their assignments, but being taught how to do it. And I told you, this can be looked up quite easily.

Best ResponseYou've already chosen the best response.0Yes, you told me to "look it up." That's not very helpful. It's more rude than anything. If I knew what it was, I wouldn't have posted this.

Best ResponseYou've already chosen the best response.1so if cos1(1/sqrt(2)) = B means 1/sqrt(2) = cos(B) Does that help at all ?
