the inverse cosine of negative 0.947
Put it in your calculator...
The sequence of keys in my old ten dollar calculator is
.947 +- 2nd COS
Other calculators have different keys strokes.
If you want to be neat, type this into a google search window:
arccos(-.947) in degrees
To find the inverse cosine of -0.947, you can use a calculator or do it manually.
If you have a calculator, you can follow these steps:
1. Enter the number -0.947.
2. Press the "2nd" or "Shift" button on your calculator.
3. Press the "COS" or "COS^-1" button.
The result will be the inverse cosine of -0.947.
Alternatively, if you want to do it manually, you can use the formula for inverse cosine:
acos(x)
In this case, you would calculate acos(-0.947).
If you prefer to use a search engine like Google, you can enter the expression "arccos(-0.947) in degrees" into the search bar. Google will give you the result directly, usually in degrees.
That's how you can find the inverse cosine of -0.947 using a calculator, manual calculation, or a search engine.
