Question about Texas Instruments TI-36 X Solar Calculator

Ie: log of 8 to the base of 2

Ad

Basically you first have to put your answer into scientific notation by pressing the 3rd key then the 6 key. The screen display should change to one big zero and two small zeros.

I was workinggon the same problem with a -log of a chemistry problem to get pH and I knew the answer because I calculated it on it TI-85, but we are not allowed to use graphing calulators on the exam (:-((() so I had to figure out how to do it on this one!

For example, I had pH =-log(2.828947x10^4)

On the TI-36X you change to scientific notation using the instructions above. Once the three zeros enter on the screen:

[4]

[-]

[2nd]

[10^x]

1^-04 should appear on screen, then you multiply by 2.828947

[x]

[2][.][828947]

then your screen will show the answer in scientific notation.

2.828947 in big numbers and in small numbers -04

From there you simply press:

[log]

and your answer will show up as a negative number. Just take the absolute value of that and you have your answer. Took me like 30 minutes the night before a huge chemistry exam to figure that out! Hope it helps someone!

Well, I am not sure, because I do not own a TI-36X SOLAR. but the answer to your example is 3. The [LOG] key on the TI graphing calculators is at position {1,6} (first column, 6th button down.)

The TI 86 has two logarithmic functions: natural logarithm **(ln) **and common (decimal) logarithms **(log)**. If you need the logarithm in any other base than e or 10 you need to use one of the two equivalent expressions

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

Here b is the value of the base of the logarithm and x is the argument (the value whose logarithm you are seeking). Of course the argument x must be a positive number.

**Note:** On the TI 86 the log function can calculate the logarithm of a complex number, according to the manual.

Here b is the value of the base of the logarithm and x is the argument (the value whose logarithm you are seeking). Of course the argument x must be a positive number.

"log(2)8" means "common logarithm of 2 multiplied by 8".

The TI-84 has three different logarithm functions.

log is the common (base-10) logarithm.

ln is the natural (base-e) logarithm.

logBASE lets you take the logarithm to any positive base.

If you want the log base 2 of 8, you want logBASE(2,8). You'll find the logBASE function in the catalog, accessible by pressing 2ND [CATALOG] ). CATALOG is the shifted function of the 0 key, the ) gets you to the Ls in the catalog.

For natural logarithms, you can use the ln
function (2ND shift of the X key). For example, the natural logarithm of 3 is
2ND [LN] 3 ) ENTER.

For logarithms to other bases, use the log function (diamond shift of the 7 key). For example, the base-2 logarithm of 16 is diamond 7 1 6 , 2 ) ENTER. If the base is 10 (common logarithms), you can omit the comma and the second argument.

You can calculate the log to any base by using the relationship logb(x) = log(x)/log(b) = ln(x)/ln(b). In words, the base-b logarithm of x is the logarithm of x divided by the logarithm of b.

So, to calculate the log base 3 of 18, press

1 8 LOG / 3 LOG =

or

1 8 LN / 3 LN =

The inverse key is marked "1/x" (second key on the third row). The natural logarithm key is marked "LN" (fourth key on the top row).

Hi,

Sorry to contradict you but there are many types of logarithms, the most important ones are

**[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

Ex:

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.

Hi,

**Logarithms in base 10 :Common logarithms**

**Logarithms in base e : Natural logarithms**

Don't forget to rate the solution and don't be stingy: 4 thumbs up won't leave you any the poorer.

- The calculator has a key labeled [LOG]. It allows you to calculate the common logarithms (logarithms in base 10).
- To calculate the common logarithm of a (positive) number you type in the number, press the [LOG] key .
- Ex: 15.32 [LOG][=] gives 1.1852558765

- The calculator has a key labeled [LN]. It allows you to calculate the natural logarithms of positive numbers.
- Ex: natural log of 15.32 is entered as
- 15.32 [LN] gives 2.729159164

Don't forget to rate the solution and don't be stingy: 4 thumbs up won't leave you any the poorer.

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, )
