learn composition of functions

Let f : A g B and g : B g C be two functions. Let h: A g C be function such that h(x) = g(f(x)) h is called the composite of f and g, denoted by h = g o f. i.e., (g o f) (x) = g (f(x..

Composition of two functions or Product of two functions - Let f:AgB and g:AgB be two functions. Thus the composition of two functions f and g denoted by gof or fog is the function from A into C defined by gof = {(a,b) for some c..

Let f:AgB and g:AgB be two functions. Thus the composition of two functions f and g denoted by gof or fog is the function from A into C defined by gof = {(a,b) for some c B, (a,c) f and (c,b) g..

The urine is a pale yellow coloured fluid. The yellow colour is due to the presence of urochrome pigment formed from the haemoglobin of dead RBC's in the liver cells. It is acidic in nature and has a pH of 6.0. It has a faint anamalic odour due to the presence of urinod. It soon gets a strong smel..

Sand /Quartz : SiO 2 : 75% (will be nice if this can be a mouse over) Sodium Oxide : Na 2 O : 15% Calcium Oxide : CaO : 8% Aluminium Oxide : Al 2 O 3 : 2% (impuri..

Silica : 45% Sodium oxide : 4% Potassium oxide : 4% Calcium oxide : 3% Lead oxide : 44% Lead carbonate or oxide replaces calcium carbonate. Potassium carbonate partly replaces sodium carbona..

It has lesser alkaline and higher alumina content than soda glass. It also contains barium oxide, zinc oxide and boron trioxide instead of silic..

Nucleic acids are made up of nucleotides. Nucleotides contain a sugar and a heterocyclic nitrogenous base along with phosphoric acid. They are held by 3' and 5' phosphate bridges. Nitrogenous bases are found in nucleotides which are of two types. They are - Purines and Pyrimidine..

It has factors other than one and itself, e.g., 21 is a composite numb..
