Answer:
1.03, 1.23, 1.32 3.12, 3.21
The Lagrangian,

has critical points where its partial derivatives vanish:





tells us
, so that


Then with
, we get

and
tells us

Then there are two critical points,
. The critical point with the negative
-coordinates gives the maximum value,
.
I don’t know what the equation is but when using elimination you should cancel out opposite numbers such as 4x and negative 4x
Answer:
(-infinity,+infinity)
Step-by-step explanation:
Any real value of x can be defined with a unique output in this function.
Angle x is 33 degrees and angle y is 57 degrees i think
