Refrection of a function across the y-axis, changes the sign of x in the function.
Thus, given the function:
Refrection of the function across the y-axis will result in the function:
Refrecting a function across the x-axis, changes the sign of the function.
Thus, refrecting the function:
across the x-axis will result in the function:
The graph of and is attached.
The green curve represents the graph of the function, while the orange curve represents the graph of the function .
Thus, given the function:

Answer:
Step-by-step explanation:
Using the product to sum formula
sinxcosy = [ sin(x + y) + sin(x - y) ] , then
2sinxcosy = sin(x + y) + sin(x - y)
Given
2sin75°cos15° ← with x = 75 and y = 15 , then
= sin(75 + 15) + sin(75 - 15)
= sin90° + sin60°
= 1 +
=
