Is your equation ? If so start by squaring both sides, Then adding to both sides Finally taking the square root of both sides. Do you follow?

Do you follow? that is great thankyou so much if i want h the subject id do the same but divide doth sides by b is that correct thats so great

ok so first i would square both sides then subtract s^2 from both sides giving me h=sqrt{S^2-b^2} stephen
No, if you want to make it this way, it's a little different. Square both sides: Now, Move b^2; You see that there is a minus sign? Multiply both sides by -1: Rearrange: Now, you take the square root.
