*Make n2 the subject of the formula.
n1 sinθ1 = n2 sinθ2
*Make t the subject of the formula
A = p(1+r)nt÷n
Hopefully i have written it correctly thanks for your replies

Posted - 06/06/2013 : 12:04:28 I have not heard of making a variable the "subject" of a formula. However, I looked it up and my assumption was correct. You might want to look up how to "solve literal equations". Since you did not show us any work or ask any sort of related question besides just stating that you are new to this type of math, I will provide an example (as you will find if you do the search I suggested).: make y the subject of 5x+2y=7 You need to isolate the term(s) with the "y". That is "2y". So, subtract 5x from each side. That is 2x=7-5x Rearranging gives 2y=-5x+7 (this step is not necessary unless you are wanting standard form) Now, divide each side by 2. y=(-5x+7)/2 Distributing gives y = -2.5x + 3.5
Note, if you can solving simple equations, then this process should be familiar to you. Yes, it is a little strange but if you read about solving literal equations, you should be able to get it.
