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: 145
3.7 x 60 = 222 (how far north she drove)
1.4 x 55 = 77 (how far south she drove)
222 - 77 = 145 (how far from home)
