Good day all.
This session has ended for today
Change of subject formula is most fundamental in the world of mathematics often ask on Jamb and other exams.
Let quickly take a look at the following.
A FORMULA -Is a type of equation which shows the relationship blw different variables such as 'X' and 'Y'
The subject of a formula - is the single variable to which everything else in the formula is equal. The subject of a formula will usually be positioned to the left of the equals sign.
x = 2y + 4z
Change of Subject Formula.
Whenever the subject of a formula is to be changed, the intention is to make the value becoming the subject stand alone and remain on the left hand side of the expression.
The methods used to effect this change may be any basic mathematical principles like multiplication, addition, subtraction, division, finding square roots, etc.
Whatever operation that is used to perform the change must be applied to both sides of the expression (formula).
