PAIR OF LINEAR EQUATIONS IN TWO VARIABLES: Like the crest of a peacock so is mathematics at the head of all knowledge.
Example
At a certain time in a deer park, the number of heads and the number of legs of deer and human visitors were counted and it was found there were 39 heads & 132 legs. Find the number of deer and human visitors in the park.
(Ans:27,12)
Ans: Let the no. of deers be x
And no. of humans be y
ASQ :
x + y = 39 ---- (1)
4 x + 2 y = 132 ----- (2) Multiply (1) and (2)
On solving, we get ...
x = 27 and y= 12
∴ No. of deers = 27 and No. of humans = 12
Definition of inverse functions : Given two one-to-one functions f ( x ) and g ( x ) if ( f o g ) ( x ) = x AND ( g o f ) ( x ) = x then we say that f ( x ) & g ( x ) are i
