This result comes from using a trig identity and the quotient rule. First, we write tan(x) as sin(x)/cos(x). Then we apply the quotient rule. After doing the standard derivatives, the numerator of our fra...

To produce a good reliable study, you would first need a sufficient number of participants to represent the actual population. Therefore a large sample size (number of participants in the study) would pro...

To meet the marking criteria, you need to make sure you cover all of the assessment objectives. A well structured essay would do this effectively. For example, if one had the question, 'assess the present...

Use the product rule d(u.v)/dx = u.(dv/dx) + v(du/dx). Calculate the LHS as such first. (Demonstrate on whiteboard.) Then calculate the RHS. (Demonstrate on whiteboard.) Group the dy/dx terms on one side ...

Mutations are changes to the base sequence. The base sequence determines the amino acid sequence. A different base sequence therefore codes for a different amino acid sequence. Amino acids interact with e...
