Question

The expression ÜÜ has an infinite number of values. O A. True O B. False

Answer 1

The given expression is

$\cos ^{-1}(\frac{3}{5})$

This expression is the value of an angle in the 1st quadrant and another value in the 4th quadrant

Then it has only 2 values if the domain is just from 0 to 360 degrees

But if the domain is open from -ve infinity to infinity, then

There are an infinite number of values to the given expression

Then the answer is true
