It is important to note that bases on the DNA (and mRNA) are read in separate sets of 3s along a DNA/(mRNA) stand (this is called a triplet code in DNA, or the codon in mRNA). So, if a base is deleted,...

The product rule is a rule for differentiating products of expressions, i.e. 2 expressions multiplied together. 

The rule is: if y=AB, then dy/dx=AdB/dx +B*dA/dx. This can be rem...

The layout of your essay is crucial. Make sure your ideas are clear and explicit - your teacher shouldn't have to decode what you mean! Use correct grammar and make your vocabulary interesting, using word...

Suppose you have 2 functions: f(x) = 3x², g(x) = log₃(x). These are arbitrary, any functions would work. Evaluate f(g(x)): let y = log₃(x) ( = g(x) ), then f(g(x)) = f(...

The most important thing to remember when differentiating implicitly is that y is a function of x. Rewriting y as y(x) often makes it much clearer. For example, evaluate d/dx (y²): using the...
