전체효과
편미분계수
편도함수
전미분
Answer explanation
편미분은 각 외생변수를 독립적으로 계산하는 것을 의미하며, 이때 편미분계수를 구하는 것이 중요하다.

다변수함수에서 독립변수와 외생변수가 구분되는 경우, 어떤 점에 주의해야 하는가?
전체효과를 무시해야 한다
편미분을 사용해야 한다
간접효과를 무시해야 한다
전미분을 사용해야 한다
Answer explanation
When distinguishing between independent and exogenous variables in a multivariable function, one must use partial derivatives to account for the effects of each variable separately.

전미분량을 계산할 때, 다른 변수는 고정되어 있고 x1이 dx1만큼 변할 때의 근사식은 무엇인가?
∂f/∂x1dx1
∂f/∂x1dx1+∂f/∂x2dx2+∂f/∂xn*dxn
Δf=∂f/∂x1dx1+∂f/∂x2dx2+...+∂f/∂xn*dxn
Δf≈∂f/∂x1dx1
Answer explanation
When calculating partial derivatives, the other variables are fixed, so the approximation when x1 changes by dx1 is Δf≈∂f/∂x1dx1.
