The marginal product, MP;=dy/dx;.Y is output
The marginal product, MPi = d y / d x i . Y is output

The technical rate of substitution (TRS): o With d y 0 along any isoquant, TRS (Xx)=dx/dx =-MP1(1,x2)/MP2(K1,X2)
The technical rate of substitution (TRS): ⚫With d y = 0 along any isoquant, TRS (x1 , x2 ) = d x2 / d x1 = – MP1 (x1 , x2 ) / MP2 (x1 , x2 )
