Cosine values are between -1 and 1. The arcosine domain is between -1 and 1. The value you have is out of range.

How do you change the interval for a arc cos


I'm not sure of the question, but to plot arccos set mode to: graph='function' and angle to 'degrees' (for example). Go to WINDOW and set xmin=-1, xmax=1, xscl=0.1, ymin=0, ymax=180, yscl=50, and xres=1. Press GRAPH. You will get a plot of arccos from -1 to 1.

Ti-Nspire gives me coordinates in radians when my mode is set to degrees.


That is a round-about way to solve cos(x)=0.543 by graphing. Use the inverse function of the cosine arccos or cos^-1
If cos(x)=0.543 then x=arccos(0.543)
To graph a trigonometric function it is more natural to use the radian as the unit. However in geometry it is more common to use the degree. To solve an equation like x=arccos(0.543) where you want the answer to be degree, change the document settings to make the default angle unit the degree.

Make the graphing angle unit the degree and set that as default by selecting Make Default and press Enter.

How do I input secant^2


Secant is the reciprocal of cosine
sec(x)=1/cos(x)
Do not confuse it with the inverse of the cosine function, which is arccos(x) =cos^-1(x)

My calculator wont graph arccos? please help


Make sure x is in the range [-1, +1]. The arccosine function is undefined for arguments whose magnitude exceed one.

How do I get -tan,-sin,-cos for inverse ratios


If you want the inverse trig functions (arctan, arcsin, and arccos), press the yellow 2nd key before pressing the appropriate trig function key. If you want a negative value, press the +/- key between the decimal point and = keys.

How do i enter sec^-1(1.85)


You cannot enter it on the calculator but you can use the relation arcsec(z) =arccos(1/z)
On your calculator arccos is represented as cos^-1.
Here is a screen capture from a calculator that has the function. The arcos is computed along with the arcsec for angles in radians (top 2 lines) and in degrees (bottom two lines).

I know the cosine and need to know how to enter it to get the angle. The cosine is .5553, what do I push to find out the angle?


2ND cos^(-1) . 5 5 5 3 ENTER

arccos is the same key as the cos, two keys above the 8. The result will be in whichever angular mode you have selected. To change the angular mode, press MODE and select between "RADIAN" and "DEGREE".
