a calculator with 4 functions!!!
Well, darling, to calculate log base 2 on your TI-86 calculator, you simply press the "LOG" button, then type in "2" and hit enter. Voila! You've got your answer. Now go forth and conquer those logarithms like the math boss you are.
The anti-log is "10^x" listed above the "LOG" key on a TI-86 calculator. All you have to do to use it is press the yellow "2nd" key (this means shift) and then press the "LOG" key.
On my CASIO fx-115MS it is the "log" button you need to press the "shift" button then press log and a small "10" will appear on your calculator screen. Hope this helps...
you see, i don't know.
The inverse of a logarithmic function is an exponential function. So to find the "inverse" of the log function, you use the universal power key, unless you're finding the inverse of a natural log, then you use the e^x key.
Yes it is hidden you need to hit the green (Diamond) and press 7.
Unless the number happens to be a straightforward power of the base of the logs, the answer is that you cannot without some access to tables or a scientific calculator. There are Maclaurin series for the log function but without a powerful calculator, you will not get far with them.
It depends on what calculator you are using. Often, shift log is inverse log, or natural log, but it could have other meanings. Please restate the question and specify the model number of the calculator.
This depends on what function, and what TI calculator.
Let y = log3 x⇒ x = 3yTaking logs to any base you like of both sides gives:log x = y log 3⇒ y = log x/log 3So to calculate log base 3 on a calculator, use either the [log] (common or log to base 10) or [ln] (natural or to base e) function key for the log above, that is use one of:[(] [log] [] [÷] [log] [3] [)][(] [ln] [] [÷] [ln] [3] [)][(] [] [log] [÷] [3] [log] [)][(] [] [ln] [÷] [3] [ln] [)]Things in square brackets [] represent keys on the calculator; the is the number of which you want the logarithm to base 3.Use one of 1 & 1 if your calculator is a more modern one that uses natural representation that looks like maths whereby the calculation is done once you've finished entering it all and the numbers for functions follow them.Use one of 3 & 4 if your calculator is an older style one that when you press a function key it acts immediately on the number displayed on the screen.The parentheses (round brackets) are included above so that the whole expression evaluates to log3.
The calculator won't do it.On the calculator, the button marked 10x gives youthe inverse log of the number in the window.
Although it's certainly possible, the log function is one thing that's not practical to compute with pencil and paper. Typical methods are with the use of a slide rule, calculator, or tables in a book.
You can calculate that on any scientific calculator - like the calculator on Windows (if you change the options, to display as a scientific calculator). Log base 4 of 27 is the same as log 27 / log 4. You can use logarithms in any base to calculate that - just use the same base for both logarithms.
I believe anything under the level of a TI89 are allowed.
