Which type of software is used for numerical analysis?

User Avatar

Asked by Wiki User

If the questioner means what software is used to help numerical analysists with forming algorithms/methods and saving themselves minutes of repitition by doing it themselves, Maple and MatLab are commonly used. There are lots of different programmes out there, those are just the first two that I could think of and, to be honest, I think MatLab is used pretty widely.

What is the average cost to resurface a pool?

User Avatar

Asked by Wiki User

Costs for resurfacing pools typically varies on the pools finish(marble,plaster,fiberglass,etc.)as well as on the original size and depth of the pool. A typical small/medium sized personal home pool ranging from 5-8 feet deep ranges between $2,000 and $4,000, these prices covering the labor, materials and other costs.

Numerical method for solving can eqution bisection method?

User Avatar

Asked by Ashishbarasarafb5037

A root-finding algorithm is a numerical method, or algorithm, for finding a value. Finding a root of f(x) − g(x) = 0 is the same as solving the equation f(x) = g(x).

What advantage does the potentiometer method have over the fixed resistor method for voltage dividing?

User Avatar

Asked by Wiki User

Resistors with precise resistances _could_ be used in the voltage divider to assure a precise voltage. However, these are more expensive. The same results can be achieved using a potentiometer because it can be adjusted to allow for minor imperfections in it.

What other n number of unit fractions can be found that sum to 1?

There are infinitely many different ways to make groups of fractions that sum to 1.

What formula can you input into excel to come up with all the 5 number different combinations for numbers 1-39?

User Avatar

Asked by Wiki User

There is no built in function in Excel to create a list of combinations of 39 items taken 5 at a time. However, the combin function will tell you how many combinations there are. For instance, combin(39,5) = 575757.

How do you find d antilog of a negative term?

Asked by Wiki User

The antilog?

a log is an exponent, so as an antilog just means you reapply that exponent to the correct base. Log implies base 10, so antilog means use that number as an exponent of 10.

If you are using log tables, first separate the whole number part and the decimal part of the log ( they are both negative) then add -1 to the whole number part and +1 to the decimal part. (one is called the characteristic and the other is called the mantissa, but I don't remember which is which now) This creates a positive decimal that you can look up in the log table. The negative integer part becomes an exponent of 10. Put them together and you get an answer in scientific notation.

Ex: find antilog of -3.5

(-3 -1) + (-.5 + 1) ==> (-4) + (+.5)

look up .5 in the log tables and you get 3.1623 and the -4 becomes 10-4

Put them together by multiplying (adding logs means multiplication of antilogs)

to get the final answer 3.1623 x 10-4

What is the utility of 'convergence rate' in numerical computing?

Asked by Wiki User

The convergence rate is a measure of how quickly the calculations become close to the value being calculated. Alternatively, how quickly the error becomes smaller.

How do you calculate average number of nights occupied per room and the occupancy rate if the given was only the number of rooms and number of nights occupied from January to December?

User Avatar

Asked by Wiki User

Average number of nights occupied per room = Number of nights occupied from January to December / Number of rooms.


Occupancy rate = 100 * Average number of nights occupied per room /365


What is the sum of all of the positive divisors of 100?

User Avatar

Asked by Wiki User

lets see...prime factorization of 100, 2,2,5,5

so divisors are 2,4,10,20,25,50 so the sum is 111

unless you want to include 1 and 100 then the sum is 212

How many ways are there to rearrange the alphabet?

User Avatar

Asked by Wiki User

The term is factoring and basically you just multiply every number up to the number that your at. Like the alphabet has 26 letters then you would multiply 1 times 2 times 3 on up to you get to 26. Its usually written as: 26!. The exclamation mark tells you to do all this.

Asked by Wiki User

96/104 = 12/13 by dividing the numerator and the denomiator by the highest common factor which is 8
