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
Answer:
so the equation would be 4x (because he buys 4 books) + 0y (because he didn't buy any CDs) = 32 (or it could be $32). The slope would be 4.
