-2^-8 * -2^8
would simply be 1.
Hope this helps. Don't forget to brianliest!. :)
Answer:
The main difference is that one has the equal sign before it while the other has it after.
You can decide which one to use based on each individual expression. If you are still simplifying, put it like this: ()=. If you are done simplifying and have your answer and are using a parenthesis, put it like this: =()
Step-by-step explanation:
In the equation

Answer:
It returns the angle whose cosine is a given number.
Step-by-step explanation:
For every trigonometry function, there is an inverse function that works in reverse. These inverse functions have the same name but with 'arc' in front. (On some calculators the arccos button may be labeled arccos, or sometimes cos-1.) So the inverse of cos is arccos etc. When we see "arccos x", we understand it as "the angle whose cosine is x"
cos30 = 0.866 Means: The cosine of 30 degrees is 0.866
arccos 0.866 = 30 Means: The angle whose cosine is 0.866 is 30 degrees.
Use arccos when you know the cosine of an angle and want to know the actual angle.
