Integrated: [x^3+2ln(x)] Sub in 3 and K: [3^3+2ln(3)-k^3-2ln(k)]Simplify: 27-K+2ln(3/K)—> K cannot = 0 otherwise ln(3/k) would have an undefined value, as would ln(k)
Simultaneous equations are equations that have one or more unknown values. There are a multitude of ways to solve simultaneous equations, however the elimination method is the most common at GCSE level ma...
Reactions can be explained in terms of loss and gain of electrons. Oxidation is Loss of electrons and Reduction is gain of electrons. When electrons are lost oxidation number increases, whereas reduction ...
