Is [tex]\frac{∂y}{∂x}×\frac{∂x}{∂z}=-\frac{∂y}{∂z}[/tex]?
Try using the simple example z = x + yNo, the chain rule does not involve such a minus sign.
Why are you asking?
Is there a general formula for partial derivatives or is it a collection of several formulas based on different conditions?In that specific case, the equation is true but it is NOT "the chain rule". Your initial post implied that you were offering this as a general formula derived from the chain rule.
