SOURCE: Random based logarithms

to do logarithms with other bases, use change-of-base. let's say you want to do log base 5 of 25. for clarity i'll write this as log(5) 25. you would have to do log(10) 25 / log(10) 5 to get 2. key sequence: [LOG], 2, 5, ), / (divide), [LOG], 5, )

SOURCE: solving multiple non-linear equations

Type it like this: solve( equation1 and equation2 and moreEquations, {list of variables to solve for})

Put all of your equations right after the opening parenthesis separated by the word and, then a comma, then within curly braces each variable you want to solve for each separated by a comma.

SOURCE: I am using the TI

Scientific mode is a display mode. It concerns the display of results. If the number are too small or too large they will be displayed in Scientific mode, because the screen does not have an unlimited number of digit positions.

Regarding the dots. A number followed by a radix mark (decimal mark) is considered to be a floating number, while the same number without a decimal mark is considered an integer (whole number).
The CAS is able to do symbolic and exact calculations, so that distinction between floting and integer numbers is important. Sometimes, to force a result to be displayed in its decimal representation all it takes is to append a decimal mark at the end of an integer.
Hope it answers your queation.

SOURCE: I want to know how

There are a lot of ways to do it. One is to write a program using the cubic formula. If you just want the roots, use the solve() or zeros() functions.

For example, to find the zeros of x^2-6x^2+11x-6, enter

Note that solve() has "=0" in it while zeros() does not.

solve() will give you an answer of
x=1 or x=2 or x=3
while zeros will give you an answer of
{1 2 3}
which plainly are the same thing, just expressed differently.

No instructions can with this calculator. How do I do simple equations without giving the variable a stored number? It would be nice if these things came with a sampe page. i.e. 3x+2-4x+1. also is there...

Strange. The calculator comes with a Getting Started manual. In any event you can download an electronic copy from
From the associated icon of the calculator, I surmise that you have TI Nspire without the CAS (Computer Algebra System). Unfortunately, this version of the Nspire cannot perform symbolic algebra. It will use the distributive property by itself if you feed it expressions without letter symbols. If you type in expressions with symbols, all symbols must have a value stored in them. The exception is instances where you are trying to solve an equation (or a systems of linear equations).

How to program the calculator TI-nspire to solve the quadratic formula

Whay would you want to go through the hassle of writing a program to solve to solve a quadratic equation`The calculator has two buit-in command to do just that. It has Solve and cSolve (for complex solutions).

Open a calculator sheet, and on the command line, type in solve(ax^2+bx+c=0, x), press ENTER and wait for the solutions

This calculator cannot solve equations and does not have an x key. You will require a calculator with a computer algebra system like the TI-89 or TI-nSpire CAS.

How do you enter a logarithmic equation into my calculator?

The 30XIIS does not have the capability of solving equations. It can, however, calculate expressions using logarithms. Use the LOG key for common logarithms and the LN key for natural logarithms. In both cases, press the function key, enter the value or expression, and then ) to match the ( the function automatically enters.

The LOG and LN keys are the second and third keys from the top in the leftmost column of the keyboard.

How do i calculate limits on my Casio fx-115es? Ex. lim x->3 for (x2'-0)/x-3

Sorry, but you cannot calculate limits of functions with this calculator. It does not have a Computer `Algebra System (CAS). For that you need a graphing calculator with CAS: Casio ClassPad 300, 300PLUS, 330, HP 48 GII, HP49 G/ G+, HP 50G, TI-NSPIRE CAS, TI89 Titanium, TI 92/92PLUS, TI Voyage 200 PLT. It is still a very good scientific (non graphing) calculator
However, you can calculate numerical derivatives, and numerical integrals, solve linear and non-linear equations.

Even though this post does meet your expectations, do not let that prevent you from rating it.

Using the correct key combination to determine inverse log

Sorry to contradict you but there are many types of logarithms, the most important ones are
  1. the common logarithms (log in base 10),
  2. the natural logarithms (logarithms in base e)
  3. the binary logarithms (logarithms in base 2)
On calculators, the common logarithms are labeled [LOG], and the natural logarithms are labeled [LN].

The inverse function of the natural log function is the exponential (e^(x)), and the inverse of the log in base ten function is the function ten to the power of. It is called (sometimes) the antilog

Question What is the antilog of 3.5678?
Answer The antilog of 3.5678 is 10^(3.5678) = 3696.579068
Verification: log(3696.57908) =3.5678

Hope it helps.

How to use the Logerithmic function on this calculator


Logarithms in base 10 :Common logarithms
  1. The calculator has a key labeled [LOG]. It allows you to calculate the common logarithms (logarithms in base 10).
  2. To calculate the common logarithm of a (positive) number you type in the number, press the [LOG] key .
  3. Ex: 15.32 [LOG][=] gives 1.1852558765
Logarithms in base e : Natural logarithms
  1. The calculator has a key labeled [LN]. It allows you to calculate the natural logarithms of positive numbers.
  2. Ex: natural log of 15.32 is entered as
  3. 15.32 [LN] gives 2.729159164
Hope it helps.
Don't forget to rate the solution and don't be stingy: 4 thumbs up won't leave you any the poorer.
