SOURCE: how to calculate

It's very simple: the calculators have a default base 10 so that log x it's log x base 10 so here is some logs:
log x base y = log x / log y
log (x*y) = log x + log y
log (x/y) = log x - log y
Hope it's helped

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: 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.

SOURCE: I have a Sharp EL-531W.All keys work except for sin cos tan hyp.

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.

You can compute the logarithm of x to any base by computing log(x)/log(b) or ln(x)/ln(b). So, press
ln . 2 5 / ln 2 = or
log . 2 5 / log 2 =

I cant figure out what is the shift key on my calculator. I have a Sharp EL-531W. I tried the 2NDF key and its not coming out right.


Regardless, that is the markings on the SHIFT key on Sharp Calculators. The 2ndF key accesses the functions that are marked on the face of the calculator, not on the top of the keys.
