It is the second function of the Pi button.

First you have to push the yellow 2nd button and after the Pi button.

I hope it helps.

Enter the value then press 2nd COS.

For example, to calculate the inverse cosine of 0.5, press . 5 2nd COS =

The inverse of the log function is the power function.

For log in base 10 that inverse is 10 to a power of

More generally, let b be the base of the logarithm. If y=log_b (x) then x=b^y

For your case log=log_10, to calculate the inverse you perform 10^(-2)=0.01=1/100

On calculators the log in base 10 and its inverse share the same physical key. One is accessed directly, the other is the shifted key function.

The inverse of the common log function is the power function with base 10 (10^). It shares the same physical key as the log. You acees the function by pressing [2nd] [log]

The one-over-x key is located two rows above the 7 key. The pi key is located just to the left of that.

Of course. Just press the INV key before pressing the appropriate trig function key. For example, to calculate the inverse sine, press INV then sin.

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.

i want to get 250 tan 35 i dont know how?can u tell me plz

Come on now....there are dedicated "square" and "square root" keys on the TI-30XA....

Enter your number e.g. 4, then press the "root x" key to get 2...

Press "x squared" key to get the square of 2 = 4

There's the even more useful "y to the power x" key and it's inverse "xth root of y" key.

E.g. Enter 2, then press the "y to the power x" key, then 5, then =, answer is 32 (2 x 2 x 2 x 2 x 2). Starting with 32, pres 2nd then the "y to the power x" key, then 5, then =, answer is 2, the 5th root of 32....

pH is minus (log to base 10) of the hydrogen ion activity of an aqueous solution, or (log to base 10) of (1/hydrogen ion activity)

To get the inverse log, i.e the hydrogen ion activity corresponding to a specified pH, simply enter the pH value and press

Use the inverse log key sequences "2nd LN" or "2nd LOG" depending on whether you are using natural logs or logs to base 10
