Make a the subject of the formula from : p = (3a + 5)/(4 - a)

When doing questions like these it is best to remember that if you multiply one side of the equation you have to do the same thing on t...

2x - 9 > 3, 2x > 12, x > 6

This was a GCSE question in 2015. There are n sweets in a bag. 6 of them are orange, the rest are yellow. Hanna takes a random sweet from the bag and eats it. She then takes another random sweet and eats ...

You would use the product rule. uv'=uv- u'vdx. In this case we would allocate u= ln x and v'=1 so u'=1/x and v=x so uv=xlnx whilst u'v=x/x=1 so we would have xln(x) -1dx. Next we would get xln(x)-x +c

Option 1 - Differentiate using product rule giving dy/dx = cos²(x) - sin²(x). (2 marks) Subbing in x as pi (1 mark) then gives (-1)² + (0)² . ...
