i have a problem i have to rearrage the formula to make P the subject but it isn't working!!! someone please answer this question and show the workings ahhhh! A 1 -- = ------ P 1+P A over P equals 1 over 1+P
A / P = 1 / (1+P)
A(1+P) = P (cross-multiplying)
A + AP = P 9multiply out brackets)
A = P - AP (terms containing P to one side)
A = P(1 - A) (take out P as common factor)
A / (1 - A) = P (divide both sides by (1 - A) )
If your Maths teacher is any good he will tell you the same as sohcahtoa......................... I think that person could well be a maths techer with a user nsme like that!!!
