Write a program to calculate the current equation

           L  1 2  
    p  2   1  sin   
              4           
           g          2 
Where p is the period of pendulum in seconds,
 g=980 cm/sec2 (acceleration), L is the
 pendulum length in cm,  is the angle of
 displacement in degrees.
                Assignment 2
Suppose that the gas company bases its charges
  on consumption according to the following
  table:

           Gas Used                   Rate
       First 70 cubic meters    $5.00 minimum cost
       Next 100 cubic meters   5 .0 ¢ per cubic meter
       Next 230 cubic meters   2.5 ¢ per cubic meter
      Above 400 cubic meters   1.5 ¢ per cubic meter
     Continue of assignment 2
Meter readings are four-digit numbers that
 represent cubic meters. Write a program in
 which the meter reading for the previous
 month and the current meter reading are
 entered and then the amount of the bill is
 calculated. The current reading may be less
 than the previous one; for example the
 previous reading may have been 9897, and
 the current one is 0103. Use IF statement.
                   Assignment 3
Write a program to read a set of numbers, and
 calculate the mean, variance, and standard
 deviation of the set of numbers. The mean and
 variance  of numbers x1, x2, …, xn can be
 calculated using the following formulas:
                                                   2
          1    n
                          1    n
                                   1       
                                            n
mean  x   xi           xi  2   xi 
                                 2

          n i 1          n i 1   n  i 1 
The standard deviation is the square root of the
 variance.
                    Assignment 4
Write a program to read a collection n of sets k of
 positive numbers, and calculate the mean,
 variance, and standard deviation for each set k of
 numbers. Write i for 1,..,i,..n and the
 corresponding calculated values in a file. The
 mean and variance of numbers x1, x2, …, xk can
 be calculated using the following formulas:
                                                     2
             1  k
                             1  k
                                        1  k
                                                 
 mean  x   xi           xi  2   xi 
                                    2

             k i 1          k i 1    k  i 1 
The standard deviation is the square root of the
 variance.
                  Assignment 5

Write a program that includes a function that
 calculates the equation F= xn sin x. Write the
 values n, x, and F on the screen and in a file
 ‘data_f.data’. Repeat the program for positive n.
                Assignment 6
Write a program that uses a module that calculates
 the equation:
                          n
                    x sin x
                 F
                       n
Both denominator and nominator are calculated by
 two different functions. Write the values n, x, and
 F on the screen and in a file ‘data_f’. Repeat the
 program for positive n.
                Assignment 7

Write a program that reads the diameters and
  heights of several right circular cylinder and
  displays the circumference, total surface area
  (including the ends), and the volume of each.
Circumference (C)= 2  r ; where r is the radius
Total surface area = C (h+r); where h is the height
Volume =  r2 h. Use one subprogram to calculate
  above equations.
              Assignment 8

Write a function that accepts an integer N and
 returns an array containing the first N
 square root of

          1, 2 , 3 , ...., N

Repeat the program for positive N.
                  Assignment 9
Write a program to read an array of numbers from
 the user, and use one subprogram to calculate the
 mean, variance, and standard deviation of the set
 of numbers. Use query control method to repeat
 the program. The mean and variance  of
 numbers x1, x2, …, xn can be calculated using
 the following formulas:
            1 k
  mean  x   x j
            k j 1
                                1 k
                                xj  x

                                                 2




The standard deviation is the square root of the
 variance.
