The function is not invertible if you think of it as
because it is not injective:
So, if we restrict the domain to the positive numbers only:
Note that the range is actually , so we can be more precise and write
To find the inverse, we solve the expression for x:
But since we restricted to positive values of x, the inverse is

Answer:
sin (140°)
Explanation:
Angle addition formulas are used to express the trigonometric function in terms of the sum/difference between two angles α and β
These rules are shown in the attached image.
Now, the given expression is::
sin97°cos43°+cos97°sin43°We have:
α = 97°
β = 43°
Comparing the given formula with the general formulas in the image, we would find that the given formula represents the sum of the sin of two angles.
Therefore:
sin97°cos43°+cos97°sin43°
= sin (97°+43°)
= sin (140°)
Hope this helps :)
