I can't find lo and reciprocal functions tabs.

There is no log (base 10) button on a TI-89. It's buried in the CATALOG as log(. As a shortcut, you can do ln(#)/ln(base), where # and base are replaced with what you want. For the inverse of a log, do the base raised to the part on the other side of the equals sign. So, log(x) = 2 would become 10^2 = x.

Hi there,

Save hours of searching online or wasting money on unnecessary repairs by talking to a 6YA Expert who can help you resolve this issue over the phone in a minute or two.

Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

Here's a link to this great service

Good luck!

It's the shifted function of the x^-1 key, located just below and right of the big round cursor pad, above the log key.

It is much more enlightning to tell us what you want to do rather than talk about something that does not exist. And one thing that does not mean anything is that ellusive INVERSE key that everyone and his dog is looking for.

The additive inverse of a number a is its opposite (-a). The key to use is the change key (-).

The multiplicative inverse of non-zero number a is its reciprocal 1/a

The inverse of the natural log (LN) function is the EXPONENTIAL function e^(x). On most calculators if one function is accessed diectly (the marking is on the key), its inverse is accessed by pressing [SHIF] (Casio, or [2nd] (TI) or [2ndF] (Sharp).

The inverse of the function raise 10 to a power [10^x] is [LOG]

Similarly, the inverse of the sine function SIN is the arcsine [sin^-1]. To access the latter, it you press [2nd][SIN]. The same is true for arcosine [2nd][COS], and arctangent [2nd][TAN]

The inverse of the square functions [x^2] is the square root function [2nd][x^2]

Inverse of x^3 is cubic root

This is just a quick overview.

For the reciprocal of a number, enter the number then press the key marked with an x^-1. You might have to use the SHIFT key first. For inverse of trigonometric functions use the SHIFT key followed by the function name. The inverse of LN is e^x. The inverse of log is 10^x. To calculate the inverse of a matrix, enter the name of the (already created) square matrix then press x^-1.

Open the yellow tab on the side of the blade guard and lift the blade out. Install a new on and close the tab. If the blade has been damaged, it may need to be pried off the locating pin at the attachment point.

Check your power supply if have a supply input to the motor of your saw,check also the fuse...if no problem in your power source/supply you can browse or check this site to get some information or guide on how the saw function

I have a powermate 18v reciprocating saw that is missing the small tab that holds the blade in place..How can I get one?

u can change ur logon or lo off sound but not standby sound

and to do that go to control panel and open sound in the new window opened click the sounds tab and there browse to the down of list for changing log on or log off sound

Hello

A set a parentheses would sure help remove any ambiguities.

I assume your equation is 0.5 =log(lo/lt)

There is an equivalence

**y=log(x) is equivalent to x=10^y**

You can write

**10^(0.5)=10^(log(lo/lt))**

But 10^(log(x))=x, thus

10^(0.5)= lo/lt

and lo/lt=square root of 10

Here is a screen capture to convince you.

Hope it helps

We had to send our saw to repair center to install new lever. Fortunately, still under warranty.

The 3 trig functions most commonly

used in triangle calculations are

sine = Opposite/Hypotenuse Co secant = Hypotenuse/Opposite

Cosine = Adjacent/Hypotenuse The reciprocals are Secant = Hypotenuse/Adjacent

Tangent = Opposite/ Adjacent Cotangent = Adjacent/Opposite

Hope this helps Loringh
