When considering extracts from literature, it is essential to focus on the overall concept that the author wants to convey. This may be identified as the main theme of the text which will guide our interp...

This is a question based loosely around the specification of the OCR A-Level Physics B course, requiring the student to recall two important quantum mechanical relations, first with one from the A2 part o...

First, we want to convert the equation to a simpler form involving just one function of x. Squared trigonometric functions are normally good candidates for simplification, thanks to the trigonometric iden...

Answer: sin^3(x)/3 + c
The student can either solve by inspection by noticing that the derivative of sin^3(x)=3sin^2(x)cos(x).
OR
The student can use the longer method of integration by par...

When solving equations like this, the most important thing to remember is that you must do the same thing to both sides. First multiply out the brackets, multiplying the x and the 4 by 2, giving 2x+8=x+10...
