How do you solve cos x 0.4 for 0 to two pie?

I assume that you want to solve cos(x) = 2*pi, not pie! arccos(0.4) = 1.1593 radians. This is the solution in the range 0 to pi. There is another solution which is at 2*pi - 1.1593 = 5.1239 radians. Note that arccos appears on most calculators as "cos to the power -1".

How do you find inverse cosine on a TI 84?

To find the inverse cosine (arccos) on a TI-84 calculator, press the "2nd" button, then the "COS" button, which is located above the "COS" key on the calculator. This will bring up the arccos function. Enter the value for which you want to find the inverse cosine and then press "ENTER" to get the result. The answer will be displayed in radians by default; you can change the mode to degrees if needed.

This would be the arccos(21/25), which is 32.859880378889108736588042568 degrees! lol


If y equals arc cos 0 then y is equal to 0 1 90 or 180?

arccos(0) = 90 + 360.n (n is an element of the integers) and 90 and 360 are in degrees. Therefore if the answer is in the subset 0<x<360 or something similar, Then the answer is 90.
