1. The problem statement, all variables and given/known data Calculate tan(arcsin(1/7)) 2. Relevant equations arcsinv = x => sinx = v sinx = (opposite/hypotenuse) (in a right-angled triangle) tanx = (opposite/adjacent) 3. The attempt at a solution Well I realize that arcsin(1/7) is an angle. Let's call it v. I also know that arcsin(1/7) => sin(v) = 1/7. So i try to picture myself a triangle like this: After this I'm lost. I'd like to use tanx = o/a, but I only know the value of o. I'm not sure how these kind of problems are solved. Any ideas?
