How do you find the arcsin(sin((7pi)/6))?
1 Answer
The answer is:
The range of a function
It means that we have to find an angle
From trigonometry we know that
for any angle
This is easy to see if use the definition of a sine as an ordinate of the end of a radius in the unit circle that forms an angle
We also know that sine is an odd function, that is
We will use both properties as follows:
As we see, the angle
