Press Mode, use cursor to find the Exponential format and select engineering.

Sorry you cannot do that in any calculator. A fraction is a rational number, a root of any index is GENERALLY an irrational number. Some exceptions do exist, but in general NO. Square root (9/16) =3/4

There is no points of inflection for this function. See cap images below.

About 2.205 pounds.

The xmin and xmax values are the left and right endpoints (respectively) for the x-axis. In window settings type - pi and + pi for your request. At fist type diamond button and then F2 to get window menu

As an example, to calculate the natural logarithm of 2, press 2nd [ln] 2 ) ENTER . If the calculator displays "ln(2)" then press diamond ENTER to convert the symbolic result to numeric. If you want the results to always come out in numeric form, press MODE, down-arrow to the

There isn't one. Unlike the TI-83/84, the TI-89 lets you use any name for lists. If you want a list (or any other item) named "L1" you can spell it out by pressing ALPHA 4 1.

n1 and n2 are integers. The proportions p1 and p2 must satisfy the conditions of the Hypothesis you are testing. p1 not equal to p2, p1 < p2, p1>p2.

If you are truly talking about the the TI89 calculator there is no command to set Diagnostics ON. This is a command for the TI 83/84 Plus. In the TI 89, the correlation coefficient is displayed by default in the statistical result screen. In the Ti83/84 open the catalog: Press [2nd][0] (CATALOG). Press D, then scroll from there until the line DiagnosticOn. Select the line and press ENTER.

An implied multiplication happens when you put two names of variables one after the other without actually entering the multiplication sign (* or cross). The calculator is interpreting this as a multiplication and is telling you it is wrong to do so. I suspect this can happen if you use a variable name made up of two or more letters without first defining the variable. If you use a variable called ax or xa without defining it before it is called, the calculator interprets that as variable a times variable x.

if the Calculator is frozen it need Hard reset it can be done only in componenet level

Perhaps you have some data stored in the x variable.

With the calculator on, press [2nd] then the minus button. This brings up a list of all the saved data in the calculator. Look through the far left column of the list for x.

If you find x in the list, highlight x, then press F1, and then select delete.

Now it should work like normal.
