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
