Question about Casio FX-115ES Scientific Calculator

I have to calulate things such as f(31) = 13.49(.967)^31 - 1. How would I do this? In my math book it says that scientific calculators have a y^x key but I don't see one. PLEASE HELP ME!!!

The y^x button is right next to the x^2 button. It is labled with an x raised to a square box (which I will write as x^box). Thus, if you enter (for example)

2 x^box 5 = 32

I need help on finding the EE or E in casio fx-115es

im taking chemistry is a easy steps to follow this when solving exponents

Continuous interest calls for an exponential function. Read your theory and use the exponential function key on your calculator: usually marked e, e^x. It may also be the shifted LN key.

Hello there,

First you need to find the P'rime factors' of 5765 which are 5 * 1153

Therefore the Exponential form of 5765 is 51 x 11531

You MUST find the PRIME FACTORS

(That means the two Prime numbers that when multiplied together gives the answer.

. Go here to see how. to 'manually calculate like we used to do it,

Nowadays just search for**'Prime Factors Calculator**' on your search engine.

Simplifications of logarithmic expressions are based on the properties of logarithms

log(1)=0

log(a/b)=log(a)-log(b)

log(a^n)=n*log(a)

log_b(x)=log(x)/log(b)=ln(x)/ln(b)

As to exponentials you have

e^(0)=1

e^(-a)=1/(e^a)

(e^a)*(e^b)=e^(a+b)

(e^a)^n=e^(na)

That is the gist of it.

But I do not think that your calculator is able to handle any scientific calculations.

I think it is case of mistaken identity. There is a function called the power function. The general form of it is a*(b)^x or a times (b) to the power of x. a is just a constant factor (not equal to 0) and b is the so-called base ( also different from zero). Personnally I call this function the power function, but you find it is often called the **exponential function.**

The exponential function**e^x **is similar to the power function. The main difference is that its base is a certain irrational number called e (=2.718281828...).

What you want to do, as far as I can guess is to calculate 2000*(1+0.12)^20.

Simplify your life and set 1+0.12 as 1.12, and type in 2000 [*]1.12^20=

1.12^20=9.646293093. Multiplied by 2000, this gives you a final result 19 292.58

**To enter the the power use the key marked as [X^y], [Y^x] or [^]**

Ok, try these two things and you should be just fine.

1.) Check your range for your graph. It is possible that the range you are using isnt large enough to show the curve. Also try using Z-fit vs Z-st. These are options that your calculator will give you once the equation is graphed.

2.) Place a parenthesis around the 2x, make sure that you and the calculator are both using the same order of operations. This move mill ensure that the calculator will multiply the variable, x, by two and then do the exponential.

This should do it!

Happy Graphing!

Hello,

There is no key dedicated to**e, **the base of natural logarithm, the same as there is for pi. However you can find it as the VALUE of the exponential function e^(x) for x=1. To obtain the VALUE of **e** you press [SHIFT] [ln] to access e^x, enter 1 and press [EXE].

Thus

[SHIFT][LN]1 [EXE] gives 2.718281828.

If you need that numerical VALUE often you may want to store it into a variable, say E. To do that

[SHIFT][LN]1 [-->] [APLHA] E [EXE]

From experience, I know that it is not the VALUE of**e** that you need but the symbol **e** to define the exponential function. If you press [SHIFT][LN] you get a syntax error. You can never see **e **in a multiplication, addition, or other arithmetic operation.

In this calculator, the** e **is first and foremost the symbol for the exponential function. If you need to draw the exponential function of X

you press [SHIFT][LN] X. Parentheses are not needed for simple arguments as this one, but if the exponent is a complicated expression parentheses are needed.

If you mean exponential of X you type [SHIFT][LN] [X,theta,T], but if you want exponential of (x-3z+ 0.5 y^2), you must enclose the argument (the object of the function) between parentheses

[SHIFT][LN] [ ( ] x-3*z+ 0.5*y [^]2 [ ) ] [EXE].

Hope it helps.

Hello,

You are not using the correct syntax of the exponential function.

**[SHIFT][e^x] ( number)** .

[SHIFT][e^x] 1 EXE] gives 2.718281828

[SHIFT][e^x] [(-)] 3 gives 0.04978706837 . The (-) is the change sign to the left of the [EXE] key.

For simple arguments the parentheses are not necessay, but it is safer to use them to avoid ambiguities and erroneous results.

Hope it helps.

The inverse of the common log is the raise 10 to a power. the inverse of the natural log is the exponential. The log and the antilog share the same key, one is accessed directly the other as a seconf/shifted function. Same thing for the natural log (ln) and the exponential.

Hello,

Yes it does. All scientific calculators do logs, power, roots, exponential, trigonometric functions. Most do also hyperbolic and inverse hyperbolic functions.
