Having graphed a Sin function and a straight line simultaneously, I wanted to find the Y-value at X = 1 of the Sin function. So, naturally I hit [2nd] [CALC] and executed the Value function, having X = 1. However, when I hit [ENTER], the calculator froze completely and all keys became unresponsive.

The problem persists even when the four batteries are removed, replaced and the calculator is turned back on; all keys still remain completely unresponsive.

When four *new* batteries were used, the calculator resumed normal functionality. However, again, when the Value function on the same pair of graphs was used, the calculator again froze, turning all keys unresponsive yet again.

Any assistance with this problem would be greatly appreciated.

Try pressing the "On" button a couple times. That should work

There are several ways of doing this.

Since you're using a graphing calculator, you can always graph it as a function of 'a' and use the graphical tools.

Another way is to use the solve() function. For example, to find the value of a where the integral of sin(x) from 0 to a equals one, enter

solve(fnInt(sin(X),X,0,A)-1),A,1.5)

solve( and fnInt( are accessible through the CATALOG. The 1.5 is an initial guess.

Enter the function using the Y= editor. Pressing [ 2nd ][Graph] (table) will display the table. You can then press [GRAPH] to see the grapg. If you want both graph and table side by side use the split screen feature.

To do so press [Mode]. Scroll down to the last line Full Horiz G-T. Highlight the option G-T. Press the Graph key.

Having gone over a month without a response to my query, I assume it was just a matter of angular modes.

That is simple. It is a function like any other.

Press the key marked [SIN]

Screen displays sin(

Enter the value of the angle (make sure the current angle unit is the appropriate one).

Close the right parenthesis and press [ENTER]

While the domain of the sine function is the whole of the real line, it range spans the interval [-1,1]. In other words the sine of an arbitrary angle is imperatively somewhere in the closed interval [-1,1].

So when you want to find the arc sine corresponding to a given value of a sine function, you cannot give as argument to the arc sine [sin^-1] a value that lies outside the interval [-1,1].

For your case, the argument is 60 and it is outside the permitted domain [-1,1]. That is why the calculator protests by signaling a domain error.

Hello,

Clear all ram

[2nd][MEM][7:Reset][1:All Ram].

To enter a function to graph ex: Y1=sin(x)

Press function key [Y=].

On first line where i says Y1= , enter the function [SIN][X,T,theta,n][)][ENTER]

Then press [GRAPH]

If graph is too flat adjust the window by pressing [WINDOW] and hoose different values for Xmin, Xmax, Ymin,Ymax.

Hope it helps.

Your calculator is set in radians. Press mode key. Arrow down to 3rd line. Highlight degree and press enter. Your calculator is now in degrees, not radians. To get out of the mode screen and back to home screen, press 2nd and then mode.

Turn off transformers. Go to apps and go all the way down until you reach transformers then hit enter. Then a menu should appear and hit uninstall that should fix it.

My calculator is completely unresponsive except for turning the power on and off. I have even taken out the batteries and replaced them, but the screen is still frozen.
