To answer this question you need to use the quotient rule. dy/dx = (vu' - uv')/v2.
U = cos(x) which differentiates to -sin(x) so u'= -sin(x)
v = x so v' = 1
Therefore, dy/dx = ( -xsin(x) - cos(x) ) / x2see more
The start of a personal statement is often the hardest bit. I think it's best to try and convey why you want to study your course without using clichés that entrance examiners will have heard thousands of times before.
In a series circuit, the electrons passes through each component in order before returning to the cell. In a parallel circuit, there are different paths for the electrons to take so the current splits depending on the resistance of each path. The voltage across each path remains the same.see more
