ATP is a molecule called adenosine triphosphate, used to provide energy for various reactions within the cell and hence sometimes called 'universal currency' of the cell. ATP molecule is made of adenine, rib...

For this question I would consider different methods for finding the roots of quadratics and remind the student that an exam could ask for a particular method to be used (as on one of the recent GCSE maths p...

Firstly I would state the substitution rule, letting 5x Cos(3x)=w(x), and differentiating with respect to w(x). This gives y'(x)=2 w'(x) (w(x)).I would then demonstrate the product rule stating where u and v...

A good first step to answering questions on specific issues or processes would be to give a clear definition of the subject, in this case, fossil fuels. If you cannot immediately think of what to write this ...

You first calculate the delta of the equation: delta = b^2-4 a c = 16 - 16 = 0 => the solution is double.x1,2 = (-b±sqrt(delta))/2/a = 4/2/4 = 1/2 which is real.so the solutions are 1/2 and 1/2.
