Question

If sinA/sinB=2/3, cosA/cosB=?

Answer 1

You don't know what it is. You have two unknowns and one equation.

Answer 2

So, it's not possible to find?

Answer 3

That's what I think unless u assume that sinA =2 and sinB=3 which is dumb.

Answer 4

We can assume sinA=2k and sinB=3k. where, k is some constant. Let me see..

Answer 5

Yeah, i guess it's not possible. Thanks, and sorry for wasting your time on such a question

Answer 6

Are these just random angles or are they related somehow?

Answer 7

Actually, i needed the ratio cosA/cosB while trying a physics problem. A plank of length 2L is sliding against a wall.. Well, there are the two situations.
That's how I got the above ratio
