To find the limit of the given expression as x approaches 2, we can apply the following steps:
lim (x->2) (cos(x))^1/(sin(2x))^2
As x approaches 2:
(cos(2))^1 / (sin(4))^2
Using trigonometric identities:
(cos(2))^1 / (sin(2*2))^2(cos(2))^1 / (sin(4))^2
Again, using trigonometric identities:
sin(4) = 2sin(2)cos(2)
Therefore:
(cos(2))^1 / (2sin(2)cos(2))^2(cos(2))^1 / (4sin^2(2)cos^2(2))
And since:
sin^2(2) + cos^2(2) = 1cos^2(2) = 1 - sin^2(2)
Substitute this into our expression:
(cos(2))^1 / (4sin^2(2)(1 - sin^2(2)))
= cos(2) / (4sin^2(2) - 4sin^4(2))
As x approaches 2, cos(2) is cos(2), sin(2) is sin(2).
Hence, after taking the limit:
cos(2) / (4sin^2(2) - 4sin^4(2)) = cos(2) / (4sin^2(2) - 4sin^4(2))
This is the limit of the given expression as x approaches 2.
