Make sure you have learned previous lessons well. If you still do not understand, let me know, and we can try to work it out. By treating the other variable like a constant, the situation seems to simplify to something we can understand in terms of single-variable derivatives, which we learned in Calc 1. The partial derivative is a way to find the slope in either the x or y direction, at the point indicated. targetSize 0 / sr. It will set Scale to maintain your desired pixel size. Apply this expression to scale property and adjust targetSize parameter. If the graph is parallel to the x-axis, it looks like a function of x, and if the graph is parallel to the y-axis, the intersection looks like a function of y. Another approach would be to use expression. Which variable the function is of depends on the orientation of the graph. In this case, when we take a slice of the graph, the two-dimensional intersection of the graph and the plane looks like a single-variable function. If you don't understand that concept, it might be good to look back and review the section on derivatives. If you think back to Calculus 1 (or single-variable calculus), recall the the derivative of a function is equal to its slope at any point. Can be thought of as "a tiny change in x "
