Thanks
SOURCE: Logarithmic functions
All calculators it's the same:
log x base y = log x / log y
log (x*y) = log x + log y
log (x/y) = log x - log y
the default base in all the calculators is 10 so instead of writing log 4 base 2 you simply need to write log 4 / log 2
Hope you understand :)
SOURCE: want to solve quadratic equations on my casio 3650p super fx
Hello,
In your manual, Appendix Program Library, (Page A1) you have the listing of the problem to solve the quadratic equation. Type it in your calculator and execute it.
Hope it helps.
SOURCE: How do I graph an equation such as y= 5x + 2?
Hello,
Turn calculator ON. If you do not see several icons press [MENu].
Use arrow to select the [GRAPH] application and press [EXE].
In the entry screen, the line with Y1= is highlighted. If it is not, use arrow to highlight it.
Press the right arrow, the highlighting disappears leaving you with Y1= and the blinking cursor.
At the position of the cursor enter 5 [X, theta,T] key under the [ALPHA]. On the screen appears 5X, complete you equation +2.
Press [EXE] to store function.
If you want to draw other functions, it is time to do so on that screen.
When done press [F6:Draw}.
If the screen does not show a lot of the function, you can use the arrow keys to pan the graph.
You can also press [SHIFT][V-Window] to set the window limits.
Hope it helps.

SOURCE: Casio fx-7400G PLUS cubic solver?
Hi,
First let us repair the terminology.
I am not sure that it has a solver (solving an equation or an inequation) but you can always draw your expression as a function and explore the graph (SKTCH) to locate the roots (or zeros) of the functions (the values of the variable where the function equals zero.) That is called solving graphically.
Hope it helps.
Thank you for using FixYa and for rating this solution.

Hello,
Press [MODE] and select [1:COMP]
Press [SHIFT][MODE] and select [3:Deg]. You can also use rad if the angle you are given is in radians.
To start the conversion
Press [SHIFT][-] (Rec) screen displays Rec(
Key in the radius r , ex: 3 screen displays Rec(3
Press [SHIFT][)] (,) to enter comma separator Rec(3,
Key in the angle in degrees, ex: 57.3; screen displays Rec(3,57.3
Press ) to close parentheses; screen displays Rec(3, 57.3)
Press [=]
Screen displays
Rec(3, 57.3)
X=1.620720961
Y=2.524532346
X and Y are the values of the coordinates.
If angle is in radians, [SHIFT] [MODE][4:Rad] the command
Rec(3, Pi) gives X=-3, Y=0
I just realized that your question pertains to the FX82MS but is listed under the FX115ES (That is quite a difference) So my answer above does not concern you but I will leave it as is should anyone need the answer for the FX115ES.
Look at the enclosed screen capture for the FX82MS
