how do I enter cos^-1

 Jun 27, 2017

Accessing the inverse cosine function is relatively simple.


Step 1: Click the 2nd Button


In the top left corner of the calculator window, click the 2nd button. Clicking this allows a user to access secondary functions.


Step 2: Click the acos Button


The acos and the cos^-1 are the same thing. A parenthesis will show up. Npw, input what number you'd like to apply the inverse cosine function to.


Step 3: Close Parenthesis


For proper syntax, close the parenthesis after inputting what number you'd like to input.


Step 4: Click the "=" Button


Clicking this will make the calculator do the calculation. You're done! YEAH
