在一個方程式中,等號左邊的那個符號就是the subject of the formula.假如這個方程有N個未知數(shù),如果已知其中N-1個未知數(shù)的值,那么最后一個未知數(shù)就可以導成the subject of the formula的形式,并且求出來.
The statement V=U+at is said to be a formula for V in terms of U,a and t.
V,U,a and t are called symbols.
The single term on the left-hand side of the equation ,V,is called the subject of the formulae.
Provided values are given for all the symbols in a formula except one,the remaining symbol can be evaluated by using a calculator.
