I have the following sentence:
From Equation 1, x=1 and y=2. Since z=x+y, substituting for the numbers results in z=3.
I want to just check the usage of "results" is correct. My logic is that substituting for the numbers is a singular "act", as in the act of substituting for the numbers results in equation A.
Am I correct?
MS word has failed to enlighten me, accepting both versions without highlighting :)
In addition, the following doesn't sound right:
The static nonlinearity was modelled by firstly simple polynomial and then dual-polynomial functions, the latter of which reduces the number of parameters required and the accuracy of the model.
At first glance, I should probably change
reduce, as the functions are plural. But something is telling me the `latter of which' is needlessly complicated, so I attempt to write it as:
The static nonlinearity was modelled by firstly simple polynomial and then dual-polynomial functions, with the latter reducing the number of parameters required and the accuracy of the model.
Please advise on both the validity of the change.
