### Syntax error when using e to find natural log

Evaluate it by pressing
5 . 8 * SHIFT ln ( . 5 6 * 4 ) =

You don't need to enter "e". Just use the e^x function (the shifted function of the ln key).

### The base of a cylinder has a diameter of 6.2 cm. The cylinder is 18 cm tall. What is the volume of the cylinder?

When you have to deal with problems of this sort, you usually are given recipes or mathematical formulas which you apply to find the result. It so happens that for the volumes of cylinders, the formula to use is
Volume = Area of the base times the height=Ab*h
If the cylinder is circular, then the area of the base is that of a disk, Ab=PI*r^2`where r is the radius.
In your case, you are given the diameter (twice the radius) and the height.
Volume =PI*h*(6.2/2)^2, the unit being cm^2

To type in the value of PI, press [2nd] [^] (the latter is key under CLEAR, and above the division sign.
To raise a number to power 2 (to square it), use the key marked x with a superscript 2, or x with a raised 2.
After you have typed in all necessary ingredients in the formula, press the [ENTER] key and the calculator will give you the result.

Now, it is your turn to do some mathematics.

### Integrating 1/root(10-x^2) from -root(10) to root(10) gives pi on the TI-89 but gives undefined on the platinum TI-89. Why and is there a way to make it work on the platinum?

On the TI92 Plus, which has the latest OS for that machine 2.09 Advanced mathematics Software one gets the result Pi in EXACT or AUTO modes and 3.1415926536 in APPROXIMATE mode.
However when in EXACT/AUTO mode the calculator displays a warning message Memory Full, Simplification may Not Be Complete. (see screen capture.)

On the Voyage 200 PLT with OS version 3, the same as on the Titanium (not Platinum), I get an undefined result in EXACT MODE and 3.1415926536 in APPROXIMATE MODE.

So you can get the approximate value of the integral on the Titanium or the indefinite integral which you can evaluate between the two boundary points.

### Is algedra the only tip of math that an electrician needes to now?

In general no. He/she will need some elementary vector calculus as well if he will try solve problems regarding design of various circuits powered by AC. Some elementary integral/differential calculus will be useful if he/she wants to solve more complicated problems with respect to power/energy consumption for example.Let just say Algebra is a MUST!

### When I create a formula in a cell, hit enter, I get #VALUE. How do I get the actual result to appear, instead of #VALUE?

#VALUE? is an error indication meaning that Excel can't process the formula. It is most likely the result of a bad cell reference in your formula, for example, you may be trying to perform mathematical operations on a cell that contains non-numeric text data.

### The learning curve

Hello,
From Wikipedia.
Mathematically the experience curve is described by a power law function sometimes referred to as Henderson's Law:
where
• is the cost of the first unit of production
• is the cost of the nth unit of production
• is the cumulative volume of production
• is the elasticity of cost with regard to output[

If that is the law involved you enter it as follows

60000*500[ ^ ] [(-)] 0.415 [=] result should be 4550.705

Here
[ ^ ] is the power key, between x-square and log
[(-)] is the change sign (or negation) key in the leftmost column, just above [RCL]

Hope it helps.
