Limtation of dimension and what is relative error

Answer» 1.this method gives us no. information about the dimensionless constants in the formula. Ex 1,2,π,etc 2.if a quantity depends on more than three factors, having dimensions.,the formula can\'t be derived 3.we can\'t derive the formula containing trignometrical functions, exponential functions, log functions etc which have no dimensions 4.it gives no information whether a physical quantity is scaler or vector<br>Another example plzzzz...<br>Limitation of dimensions :It not tell about dimension of constant value, trigonometry function, and dimensions of 2 value eg. S=ut+1/2at2
