If you press the setup key then 1 under FSE it will say TAB (0-9)? enter the amount of decimal places you want and it will change that for you.

SOURCE: I need to change the time on my Sharp EL-1750PIII calculator

You can access the .pdf manual for your particular calculator here:

http://www.sharpusa.com/files/cal_man_EL1750PIII.pdf

Page 1 for how to set date/time:

“RATE SET”: To set the date, time, and tax rate, set this switch at the “RATE SET” position.**
Date:**
• Enter in the order of month, day and year, then press to complete the entry.

• Use to separate month, day, and year.

• When is pressed, the number entered is evaluated and displayed as “date” if the

value is within the following range; “Error” is displayed otherwise, and the previously set

date is restored.

Month: 1 - 12; day: 1 - 31; Year: 2000 - 2099 (in 4 digits) or 00 - 99 (in 2 digits)

(There is no entry available for the seconds value. The clock starts at zero second.)

• If the hour/minute digit is less than 10, it is not necessary to enter the first digit “0”.

• Use to separate hour and minute values.

• When is pressed, the number entered is evaluated and displayed as “time” if the

value is within the following range; “Error” is displayed otherwise, and the previously set

time is restored.

Hour: 0 - 23 (24-hour system for the hour entry), Minute: 0 - 59

SOURCE: how do I use sharp EL 531W to solve quadratic equations?

Hello,

This calculator does not have a program to which you give the equation, and which returns the solutions. Sorry. You have to use the formulas you learned.

Let the equation be ax^2 +bx+c=0

You compute the discriminant Callit disc.**disc= (b^2-4*a*c)**

1. If discriminant is larger than zero you have two solutions. Let us call them x1 and x2.

Then** x1=(-b+square root of disc)/(2*a)**

and **x2= (-b-square root of disc)/(2*a)**

2.** If disc=0** , square root of disc =0 and** x1=x2=-b/(2*a)**

3. **If disc is negative, there are no real solutions.**

To find the solutions you **replace a, b, and c **by their numerical values, to calculate disc, its square root, and calculate X1 and X2.

Hope it helps.

Hello,

Here are exemples from the manual.

Posted on Sep 25, 2009

To convert a complex number (not an equation) from rectangular coordinates to polar coordinates you do as follows

2+3[OPTN][ F3 (CLPX)][F1(i)][F6 >][F3> r ,theta][EXE]

2+3[OPTN][ F3 (CLPX)][F1(i)][F6 >][F3> r ,theta][EXE]

You cannot add rectangular coordinates to polar coordinates. You can **only add rectangular coordinates to other rectangular coordinates.** For polar coordinates you must use some specific trigonometric formulas.

Sep 23, 2014 | Casio Office Equipment & Supplies

If one or both numbers are in polar form, convert it/them to rectangular. Once both numbers are in rectangular form, simply add the two components separately: Add the two x components together, and add the two y components together.

If you're asking how to do this on a particular calculator, please specify the make and model.

if by theta function you mean the change to polar coordinates function, type in your x and y coordinate for example (3; 4) to do this press 3 (x,y) key 4 then 2nd F (the orange button) and then 8 (the theta function) and then r will be 5 and theta will be 53.13010235. If you have the polar coordinates and want to change to rectangular coordinates type in the hypotenuse (x,y) button and then the angle and then press 2nd F and 9 and it will give you the x and y coordinates.

The Pol function converts coordinates from rectangular to polar. Pol(x,y) converts the rectangular coordinates (x,y) to polar coordinates (r, theta).

Are you serious?

No calculator purchase should be solely based on such a trivial matter.

But if you are looking for a very good scientific calculator, I would suggest the new Write View EL-W506/W516/W546 calculators by Sharp, or the FX-115ES/991ES Natural Display by Casio.

With these calculators you can see what you enter displayed as in textbooks. Naturally, they all do coordinates conversions from Polar to Rectangular and from Rectangular to Polar.

No solution, but I have the exact same problem with a Sharp EL-531W calculator. Doesn't matter whether mode is degrees, radians, etc., and resetting with button in back has no effect.

To avoid errors make sure that the angle unit is THE ONE
required by your problem. To verify or to change the angle unit press
[SIFT][MODE] and select [3: Deg] for degrees, [4:Rad] for radians, or
[5:Grad] for grads.
