Historiography is a great way to boost your grade in an essay when used correctly. As well as looking at more general terms such as 'revisionist' or 'orthodox', you can look at specific historians and wha...

6a + b = 16    Equation 1
5a - 2b = 19    Equation 2

Scale up one equation so both equations have same coeffient of one variable ie 2 times Equ 1

12a + 2b = 32
5a - 2b = 19

By taking the formula F=m*a, and rearranging the make a the subject, we get a=F/m. Then by substituting in the values given we can work out that a=30/10=3. The units of acceleration are ms^-2 so...

By factorising the expression, (x-5)(x-4)=0. This means that either (x-5)=0 or (x-4)=0. By solving these equations we can work out the solutions to be x=4,5.

Research into the cognitive approach is largely based upon computor models, which uses computor terminology to describe human cognition, for example 'input' would represent sensory information from our en...
