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...}

This question is asking us to split up the fraction into two separate fractions.To begin we use one of the standard forms for solving partial fractions, this is (A/(X+1))+(B/(X+2)).To solve set the first ...

At rest the membrane potential is -70mV.

This is due to the  Na⁺/K⁺ pump, which actively transports 3 Na⁺ ions out of th...

We can immediately see that more than differentiation rule will be needed here. The expression in question is the product of two smaller expressions, so the product rule may be useful. But to apply the...

Analysing quotes can be tricky, especially when you don't know where to begin. However, specific word analysis is the area that can get you the most marks and push into the upper grade boundaries an in...
