Using a Scientific Calculator

by Ron Kurtus

The Scientific calculator will be an upgraded version of the typical hand-held calculator or computer program could be utilized. It typically has trigonometric features like sine and cosine exponential functions, such as square root, and miscellaneous mathematical functions. Some expensive scientific calculators even include graphic and problem-solving capabilities.

There are some basic scientific calculations in the School for Champions classes and have added an online calculator to utilize. You can access it from the lessons that include calculation examples. This lesson provides instructions on how to utilize this calculator.

Questions you may have include:

  • What is required to operate the calculator?
  • What does the calculator appear like?
  • What is the best way to use it?

Scientific Calculator

The online calculatoris made to function as a regular calculator. However, you be able to use your keyboard for enter numbers. It is necessary to click the numbers and functions in the calculator.

How to use it

It is assumed that you know how to use a simple calculatorto divide, multiply subtract, multiply, the number of divisions, and we'll just describe the more complicated functions.

  • Clearing
  • Memory
  • 1/x
  • sin, cos, tan, inv
  • x^2, x^y and sqrt
  • pi (pi), ln, and n!

Clearing

If you type in a number in error, you can use C to erase that number. This does not erase prior calculations.

If you'd like to delete what's displayed then click AC ("all clear"). Make sure to note this: AC does not clear the memory.

Exercise in a clear mistake

  1. Use the to activate AC to clean up any mistakes that you've done in the past.
  2. You can enter 13 + 3, however, you will realize that you actually meant to type 13 instead of 3.
  3. Now click "C" to clean all 3. Then , enter the number 13 then click + to find the correct answer for 25,.

Note

Note that different calculators have different expressions to clear the entries. A lot of calculators utilize C to clear an entry as well as AC to clear allentries, just like our calculator. However the calculator that comes with Microsoft Windows uses CE to clear entries and the C to remove all entries. You must be aware of the terminology your calculator uses.

Memory

When you do certain calculations, you may want to remember the calculation for later use. You can store a particular calculation to your memory by pressing the M+ button. Then you recall it later using the button MR. button. You erase the memory using the button for MC. button.

Make note it is important to note that The M+ will apply whatever you're displaying to what's already in the memory. So it is recommended to click M+ before adding using M+ in the event that you have recently begun using the calculator.

Add to memory exercises You want to add 1 + 2. Then multiply that by the sum of 8 - 3.Click AC to clear all.Add the two numbers and then click =.Click MC to clear the memory, and then click M+ to add the value the memory.Click AC to clear the previous addition.Then enter 8 3, =.Click * to multiply by another number.Click MR to recall what is in memory. After that, click =.You should have a total of 15.To learn how to further add to your memory simply click M+ and then MR. The 15 will be added to the three already in memory and give you 18 when you remember memory.

1/x

1/x will be 1 divided in whatever is.

  • Enter 5 and then click the 1/x to get 1/5 = 0.2

sin, cos, tan, inv

Trigonometry functions that are used in trigonometry regarding angles are sin ( sin) cosine ( cos), and the tangent ( tan).

  • If you would want to determine the sine value of an angle that is 30 degrees wide, you would input 30 and click the sin button. The answer will be 0.5.

inv

There is also the capability of reverse-travel. If you are familiar with the sine, cosine, or the tangent function, you can determine the angle in degrees for the function. This is known as the inverse ( inv) operation. These are also referred to as an arcsine or arccosine or the arctangent.

  • Enter 0.5 in the box, then click intov and then click on sin. You should get 30 (degrees) for the answer.

There are two xy and x2

x2 refers to "x squared" or x 2. This also means x times x or x*x.Clear allEnter 3 then click x^2 to generate nine. x^y means that x has been raised to the appropriate y power. In other words, if y = 3, you'd have x cubed or x 3. Utilizing this method is tricky.Suppose you wanted to calculate three 4. That's 3*3*3*3 times itself 4 times.Clear allEnter 3 then click "xy"Enter 4. Then click =.You should receive the answer 81.

sqrt

sqrt refers to what is known as the square root. It is frequently used as the symbol , however, it could not show up in old browsers.

The square root numbers is the value multiplied by itself which equals the original number.

Find the square root of 121:

  • Enter 121 and click on sqrt. You should receive an answer of 11. (11*11 = 121.)

(You can also calculate the square root using x^y with the formula y = 0.5.)

pi pi is the number 3.14159... which is utilized in many geometric calculations. It is often referred to as the Greek letter p but it might not be the case in outdated browsers.ln ln is called the natural logarithm of the number. The operation is not used much.n! n! is a representation of n factsorial. If n is 7, n! = 7*6*5*4*3*2*1. This operation is not utilized much.Enter 4 and then click "n!.

Summary

You can utilize the online scientific calculator to solve different issues. It's similar to real battery-powered calculators.
