Sorry if the question has been asked before.
I have two equations, such as
lts=22*(ss/mor)^2.2/(w*(29+N^0.4)) .... equation 1
N=(22*(ss/mor)^(-2.2)/(w*lts)-29)^(5/2) ..... equation 2
where ss, mor, w, lts, and N are variables.
the solution is to diffrentiate the first equation with respect to N then subsititue the second equation in the resulting equation from the differentiation process. Please, could you suggest a solution? Thanks in advance.

You can use 'syms' to symbolize N, w, ss and mor. Define the first equation 'Its'. Nest use the 'diff' function { diff(lts,N) } to partially differentiate.
