Question about HP 15C Scientific Calculator

Hi,

a 6ya expert can help you resolve that issue over the phone in a minute or two.

best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

click here to download the app (for users in the US for now) and get all the help you need.

goodluck!

You don't.

Angles can be measured using three different units: degrees (360 degrees in a circle), radians (2pi radians in a circle), or grads (400 grads in a circle).

Pressing the DRG key cycles through the three modes. No matter which mode you select, one of the annunciators will appear on the screen to indicate the current mode.

It means your calculator is set to degrees mode. Angles can be measured using three different units: degrees (360 degrees in a circle), radians (2pi radians in a circle), or grads (400 grads in a circle).

Pressing the DRG key cycles through the three modes. No matter which mode you select, one of the annunciators will appear on the screen to indicate the current mode.

To change the angular mode, press the blue g key and then one of the 7, 8, or 9 keys to select Degrees, Radians, or Grads. To change the display mode, press the yellow f key, then one of the 7, 8, or 9 keys to select Fix, Sci, or Eng, followed by a digit to select the desired number of digits after the decimal point.

Why do you want to get out od Degree mode. If you are doing trigonometric calculations, the angle unit is pertinent. If you are not doing trigonometry, it is irrelevant. You say you can cycle through DEG, RAD, GRAD. That is the way to set the angle unit.

**However, there will always be an indicator on the screen (DEG, RAD, or GRAD). **

Turn calculator ON.

If you see no icons, press MENU then 1: to enter the RUN screen. Press the SHIFT MODE key combination to enter (SetUp). Use down arrow to highlight the line Angle. Press the F3: key to activate the GRAD angle unit. Press EXIt to return to the RUN screen.

The calculator has three angular modes: Degrees, Radians, and Grads. You're going to be in one of those modes at all times, and the calculator will light the appropriate indicator.

You can press the DRG key to cycle through the three modes, but one of those indicators will appear on the screen at all times.

Under the screen you can see atable of values at the right of which is written MODE followed by a small arrow.

If you want to set the degree as angle unit, you press the MODE key followed by 4 (as seen in the table I was referring to).

Similarly, if you want to set RAD as the angle unit you press MODE then 5; and MODE then 6 for GRAD.

However if you just want to convert a number displayed on the screen in RADs or GRADs into DEGs , you press SHIFT then MODE then 4. your number should be converted from the unit it was expressed in into degrees.

Same thing if you want to convert into RADs: SHIFT then MODE then 5.

Hope it helps.

Read the screen capture about the MODES of this calculators. DEG,RAD, and GRAD remind the user that the angle units in trigonometric function calculations and coordinate conversions are in degrees, radians or grads. They have nothing to do with the other calculations you are doing.

You can only remove DEG by changing the angle unit to RADians or GRADs. In so doing, the new unit indicator (RAD, GRAD) will be displayed instead. There is no point worrying about the angle unit indicator unless you are performing coordinate conversions or calculating trigonometric functions or the inverse trigonometric functions.

MODE 9 cancels the FIX display format: decimal are displayed with a fixed number of decimal places (set by the user). After this key sequence the decimal display format reverts to NORM(al).

Sorry, but I think you misunderstood what the manual says. See the not on the screen capture.

True the sentence is not very clear, but what it means is the following:

All modes (except COMP) will have an indicator (with the appropriate labeling) displayed. When in COMP mode the COMP indicator is not displayed.

The truth of the matter is that computation- wise you have two MODES only : the general COMPutational mode and the Standard Deviation (SD Statistics) MODE. These two are incompatible because the key layout is different.

But to compute trig functions

But to compute trig functions

- calculator must not be in SD mode, hence it is in COMP mode
- An angle unit must be shown on display.
