Set up the auxiliary equation by letting (dy/dx) = m
So we have: m² + 3m + 2 = 0
Solve for m and we get: (m+1)(m+2) = 0Therefore, m₁=-1 and m₂=-2
Now we s...

A reaction is said to be feasible or spontaneous when the Gibbs Free Energy (Delta G) of the reaction is <0. Conversely, when the Gibbs Free Energy (Delta G) of the reaction is >0,...

This is such a commonly asked question, that I rarely address much else in my first lesson. Structuring essays is overwhelming, especially when you are comparing two literary works, looking to show off wh...

This is a typical simultaneous equations question. Using the information in the question we can write down two equations in two unknowns (let's say T=tea and C=coffee).(1) 3T + 2C = £7.80(2) 5T + 4C = £14...
