Transcribed Image Text:Underline the domain and then write the negation of the following
For all real numbers x, if sin(x) = 2, then cos^2 (x) = −3.
Negation:
Which is true: the original, the negation, or neither?
Expert Solution
Step 1
We know the sin function very well. Graph of the function is
Since the sin(x) is periodic and we see that maximum value of sin(x) is 1.
