Upon request, the transfer of degrees from decimal fraction in hours, minutes, seconds and back Create a calculator, which translates the value of an angle, expressed in degrees with a decimal fraction in degrees minutes and seconds. In the quality of the default angle value, we will use the current angle of inclination of the Pisa Tower ( 3.97 °).

#### Translation of fractional degrees in degrees minute and seconds

Degree defined by decimal fraction

Degrees, minutes and seconds

Degrees, minutes and seconds

The following calculator produces an inverse operation, i.e. from degrees minutes and seconds in decimal degrees:

#### Translation of degrees minutes and seconds in fractional degrees

Meaning in degrees of minutes and seconds

You can work with a computing program online from any device, in each case the size of the interface will adapt to your device, or you can adjust its size to your taste.

Entering numbers are made in two versions:

**from mobile devices**- Enter the display of the phone or tablet, the program interface keys**with a personal computer**- using an interface electronic display, or through a computer keyboard by any numbers

**Instructions for engineering calculator functions **

To understand the program's capabilities, we give you a brief instruction, see more detail in **Examples of computing online **. The principle of operation with the scientific calculator is: the number with which the function can be performed, then the function button or operation is pressed, then, if required, another figure, for example, the degree in the end is the equal sign.

**How to build a degree **

To raise, for example, 12 ^ 3 insert in the following sequence:

**12 [ ****x ^{y}**

**] 3 [=]**

12, X-degree key [xy], 3, sign of equality [=]

Answer: 1728.

**How to find a root cubic **

Suppose we remove the root cubic of 729, click in this order:

**729 [3√x] [=] **

729, [ ^{3}√X] "Cubic root from X", equality [=]

**How to find the root on the calculator **

Task: Find Square Root 36.

Solution: everything is simple, click like this:

**36. ****[**^{y}**√****x****] 2 [=] **

36, [ ^{y}√x] "The root of the IKSA, to the degree of igrik," degree we needed, is equal to us [=]

Answer: 6.

With this feature, you can find the root to any extent, not only square.

**How to build a square **

For the construction of the Square, the online computing program contains two functions:

**[X. ^{y}]**"X to the degree of play", [x

^{2}] "X-in-Square"

The sequence of data entry is the same as before - first the original value, then "x ^ 2" and the sign is equal, or if not a square, and an arbitrary number, you must press the function "x ^ Y", then specify the desired degree and also press ".

**For example: 45 [x ^{y}] 6 [=] **

Answer: Forty five in the sixth step. Equal 8303765625

**Trigonometric Calculator Online - Examples **

**How to make online calculation of sinuses and cosinees, tangents **

Note that kalkpro.ru able to operate as a degree, so radians and degrees.

1 rad = 57.3 °; 360 ° = 2π rad., 1 deg = 0.9 degrees or 1 degree = 0.015708 radians.

To enable this measurement mode, press the desired button:

where Deg - degrees, Rad - measured in radians, Grad - in grads. The default is the calculation mode in degrees.

As the simplest example, we will find sinus 90 degrees. Click:

**90 [sin] [=] **

Answer: Unit

Other trigonometric functions are also calculated, for example, calculating cosine 60 °:

**60 [COS] [=] **

Solution: 0.5

Similar method are calculated inverse **Trigonometric functions online on Calcpro **- Arksinus, Arkkosinus, Arctanens, as well as hyperbolic functions SINH, COSH, TANH.

To enter them, you must switch the interface by clicking [Inv], new buttons will appear - ASIN, ACOS, ATAN. The procedure for entering the previous one: first the value, then the symbol of the desired function, be it acrsinus or arcsine.

**Conversion with DMS and DEG button on the calculator **

[DEG] allows you to translate an angle from the format of degrees, minutes and seconds to decimal fractions of degrees for computing. [DMS] reverse rendering - in the format "degrees; minutes; Seconds.

**For example, **An angle of 35 o 14 minutes 04 seconds 53 Tenths of seconds will translate into tenths:

**35,140453 [Deg] [=] 35,23459166666666666666 **

We translate into the former format: 35,23459166666666666666 [DMS] [=] 35,140453

**Decimal logarithm online **

The decimal logarithm on the calculator is calculated as follows, for example, we are looking for logs for the base 10, log10 (1) or LG1:

**1 [LOG] [=] **

It turns out 0 in the end. For the calculation of the LG100 click like this:

**100 [LOG] [=] **

**Decision **: two. How to check yourself? That in general such logarithm - log to the base 10. In this case, 2 - is the degree to which you must enter the base of the logarithm, that is, 10 to get 100.

The natural logarithm is also calculated, but the [LN] button.

**How to use memory on the calculator **

Existing memory buttons: **M +, M-, MR, MS, MC. **

Add data to the memory of the program so that the MS operation will help then carry out further calculations.

MR will display you the information saved in memory. MC will delete any data from memory. M- Watch the number on the online display of the memorized in memory.

**Example **. We will make one hundred forty-five in the memory of the program:

**145 [Mr] **

After conducting other calculations, it was suddenly needed to return the memorized number on the electronic calculator screen, press simply:

**[Mr] **

The screen displays 145 again.

Then we think again, we believe, and then decided to fold, for example, 85 with the memorized 145, for this we click **[M +] **either **[M-] **85 for subtraction from the memorized 145. In the first case, the return of the final number of memory button [MR] turn 230, and the second, after clicking [M-] and [MR] to yield 60.
