So for this question you can use either the product rule or the quotient rule and I'll run through them both.First the quotient rule:The quotient rule says that if you have h(x)=f(x)/g(x)Then h'(x) = (f'(...

Firstly we need to rearrange this equation so that it contains only one trigonometric function of x (i.e. tanx, cosx or sinx) which will make it much easier to solve.

We can do this in th...

Expand (1+0.5x)4 , simplifying the coefficients. Step 1. Draw Pascal's triangle to find the coefficients       1 ;  1  2  1 ; 1  3  3  1 ; 1  4  6   4  1. As you can see, each row starts ...

To solve Inx + In3 = In6 we must follow some basic log rules, log_b(mn) = log_b(m) + log_b(n)if we compare this with the...

This question tests a variety of mathematical techniques and knowledge which is integral to A-level mathematics.

Note that the highest power of a variable function in the mentioned equatio...
