This is a very common question for those studying history, even I sometimes find myself asking the same question when approaching essays at university. Its natural to fall into a narrative style, as we of...

Use the photoelectric effect equation which shows conservation of energy between photons, electrons and the material that the electron is being freed from, hf = phi + KE_max . Definin...

In order to determine the most significant cause of business failure it is of relative importance to consider the critical environmental factors both internally and exte...

Roots = where line touches x-axis. Set equation equal to 0 as y=0 at the x-axis. Now we need to solve for the x values at which y=0. Quadratic is now 0=x^2+5x+6. Factorise quadratic: 0=(x+3)(x+2). Now you...

f'(x)= 3x^2+1/3x^(-2/3)

To differentiate you need to multiply the coefficant of the x dependent terms by the powers and then the power of x goes down by one. 

For example: differentiate f(x)...
