Using the Factor Theorem, we know that (2x + 1) = 2(x + 1/2) = 2(x - (-1/2) ) is a factor of p(x) if and only if p(-1/2) = 0, which is true. Now that we know a factor of ...

Parliament has 3 main functions. The first is scrutinising government, this is completed by select committees who check and challenge their work. For example, approving government spending. The second is ...

let f(x)=sin x f'(x) lim h-> 0 = ( sin(x+h) - sin(x))/h. f'(x) lim h-> 0 =( sin(x)cos(h) + cos(x)sin(h) - sin(x))/ h. f'(x) lim h-> 0=(sin(x)(cos(h)-1)/h + cos(x) (sin(h))/h. then as h tends to z...

In the play 'Hamlet', the main father-son bond we become enthralled in is that of Hamlet and his father. Unmistakably, their bond is powerful; it is this bond which led to Hamlet's plot for revenge. In or...

The albedo effect is the amount of light a surface reflects. Snow, for example, has a high albedo effect because it does not absorb much light and reflects back a lot of it. Roads, however, have a low alb...
