Simple waveform - something like a sine wave. Very pure sound like you used to get on the tv when that girl was sitting with the toys in the middle of the night. Complex waveform is like speech etc
        
             
        
        
        
Answer:
see explaination 
Explanation:
MATLAB script:
% MATLAB script that calculates reciprocal Fibonacci constant Ψ
% Initial Values
a0 = 1;
a1 = 1;
% Looping variable
i = 2;
% Reading n value from user
n = input(' Enter n value: ');
% Initializing sum
sum = (1/a0) + (1/a1);
% Loop till i reaches n value
while i <= n
 
% Finding term in Fibnocii series
a2 = a0 + a1;
 
% Accumulating Sum
sum = sum + (1/a2);
 
% Updating previous terms
a0 = a1;
a1 = a2;
% Incrementing loop variable
i = i + 1;
endwhile
% Printing result
printf("\n Reciprocol Fibnocii Constant: %f \n", sum);

It is true that the information provided in text aids can help us to understand a text's content before we even read it.
These text aids will contain bits and pieces from the text, which will make us understand the overall message even before we actually get down to going through the text itself. I believe it is better to actually read the text, and try to understand it on your own, before going to these aids for help.
