The expression that is equivalent to is .
Given trigonometric expression is:
<h3>What is the
value of
?</h3>
The value of is because lies in the second quadrant and the cosine function is negative in the second quadrant.
So,
The range of sine and cosine functions is the same i.e. [-1,1].
Both the functions are periodic functions with periods 2π.
Hence, the expression that is equivalent to is .
