Question about Casio PRIZM FX-CG10 Graphing Calculator

Ad

On any calculator, let's convert degrees-minutes-second to degrees and then we will do the reverse.

Let's start with the number of seconds in a minute - 60, so we must take the seconds and divide by 60 to get the number of minutes. Next, add the number of minutes. The number of minutes in a degree is 60, so we take this total and divide by 60. Now we add the number of degrees to get out final answer.

Example: 35 degrees 50 minutes 32 seconds

(32/60 + 50)/60 + 35 = 35.842222 degrees

Just out of interest, let's start with 35.842222 degrees and convert it to degrees-minutes-seconds. We know it is 35 degrees, the whole number. Now we have to determine the minutes and seconds. Start by subtracting 35 to get the decimal 0.842222. Now multiply by 60 to get the number of minutes. I get 50.5332. Subtract 50 from this and multiply again by 60. I get 31.9992, which rounds to 32 seconds.

Good luck.

You don't.

If you want to input an angle in degrees-minutes-seconds, simply enter it as DD.MMSS . See page 7 of the manual: http://www.fixya.com/support/p131668-texas_instruments_ti_30xa_calculator/manual-5027

Enter the degrees, press DMS, enter minutes, press DMS, enter seconds.

You must input all three items, even if they are zero.

The DMS key is marked with the degrees, minutes, and seconds symbols (circle/single-tick/double-tick), and is located two keys above the 8 key.

Press the DMS button to convert between decimal degrees and degrees-minutes-seconds.

The DMS button is marked with the degree, minute, and second symbols. It's located above the [ENG] key, which is located above the [8] key.

For full details, start with the "Degree, Minute, Second (Sexagesimal) Calculations" section beginning on page E-22 of the manual. If you need a manual, you may download a copy here.

Press the degrees/minutes/seconds [o ' "] button after entering each part of the angle. It will appear on the screen as the same (degree) symbol after each part, but the calculator will recognise that each part is different and compute accordingly.

Cristina,

You might be referring to something else, so let me try to knock out two birds with one stone.

The arcsine function is the inverse sine function. It will take a ratio input and produce a degree/radian output. It isn't exactly transforming anything into degrees. Instead, it is telling you the corresponding angle that goes with the ratio of opposite over hypotenuse (your input).

With that said, I am going to try to answer your question with two possible solutions.

1. To find the arcsine of a value/input (between -1 and 1) you simply have to press {[2ND]} {[SIN]} {["NUMBER"]}. For example, if I wanted the arcsine of one-half I would press {[2ND]} {[SIN]} {[.]} {[5]} {[=]}. The computer would display 30 (degrees) because the sine of thirty degrees is one-half, therefore the arcsine of one-half is 30 degrees. Inverse functions in math are often written with a faux-exponent of negative one. Inverse sine (ie arcsine) should be written in blue above the sine button on your calculator.

2. To convert a compass reading into a concrete degree measure you will NOT use arcsine. Instead, you can use the Degree-Minute-Second key which is on the TI-30X. The degree portion is naturally symbolized by the superscript o; the minute is symbolized by the single apostrophe mark, the second symbol is the quotation mark. So, to convert a compass reading of 10 degrees-30 minutes - 30 seconds you would type {[10]} {[o ' "]} {[=]} {[30]} {[o ' "]} {[ -> ]} {[=]} {[30]} {[o ' "]} {[->]} {[->]} {[=]} {[=]}. The calculator should display 10.50833333, which represents the hardcore angle measure that corresponds with 10-degrees-30minutes-30seconds. Also, it should be known that this is a much better thing to do by hand because it will deeply ingrain the basic mathematics going on. Even though we're talking about degree measures, the minutes & seconds are still at a 60 unit benchmark: meaning that there are 60 minutes in a degree and 60 seconds in a minute. Therefore, 30 minutes & 30 seconds is 30.5 seconds, which is 50.83333 percent of 1 degree. Thus, 10.5083333 degreeees. Also, you can think of it as 3600 seconds in a degree, therefore you had 1830 seconds which equated to 50.83333% of 1 degree. Thus, 10.50833333 degrees total.

Alright...I hope that helps you with either question you might have been referring to. Also, I hope you enjoyed the minor math lesson involved here. Maybe you already knew it. If that was the case then I am sorry. Either way, I own a TI-30XB Solar (among many other TI Calculators) and I highly doubt that the buttons on my calculator are starkly different from yours.

If you have more calculator or even math questions just post them on here and I'll hack away.

Arrivederci.

Enter the angle in degrees-minutes-seconds using the single-tick (') for all three parts. Do NOT use the degree and second symbols. In my TI-86 manual, it's on page 285.

Hello,

Look at the column of keys under the ALPHA key. You have the integral, the square root, and then the key that has a degree sign, an apostrophe and a double closing quotation mark. That is the one you use to enter the angle in sexagesimal notation. To simplify my task I will symbolize the key with [DMS], degree, minute , second.

To calculate cos (32° 45')

you press

[COS] 32[DMS]45 [DMS] ) and press [=] The result si 0.841039013

Hope it helps.

if you mean degrees like the degree/minute/second thing:
lets say you have 24.12
there is a button that has a dot, and 3 commas (it's located next to the negative button) that will convert that number to degrees. input your decimal, press the equal sign, and then press that degree button and it will convert 24.12 to degrees, minutes, and seconds. the solution is 24 degrees, 7 minutes, and 12 seconds.
