Implicit differentiation
take the deritivive with respect to x
first
y+2=(1/2)(x^2)-2sin(y)
take deritivitive
dy/dx+0=1/2(2x)-2(cosy)dy/dx
dy/dx=x-2cosy(dy/dx)
add 2cosy(dy/dx) to both sides
dy/dx+2cosy(dy/dx) =x
undistribute dy/dx
dy/dx(1+2cos(y))=x
divide both sides by 1+2cos(y)
at (2,0)
x=2
y=0
the slope is 2/3
The slope is -9
Y intercept is -6
Answer:
A, C, D
Step-by-step explanation:
The sum of two irrational numbers may be rational:
√2 + (-√2) = 0
so that set is not closed under addition.
___
For any of the other sets, addition of two members of the set always results in another (not necessarily different) member of the set.
Answer:
4^2(2-square root 2)
Step-by-step explanation:
C I guess I was learning this in class but I'm not sure.
