Formulae to be used: n^th term of an arithmetic sequence u_n= u₁ + (n-1)d and sum of the first n terms of an arithmetic series S_n = (n/2) * (2u₁ + (n-1...

Medicine and dentistry are very competitive courses with limited spaces, so the application process can be very long and frustratingly hard but I will take the student through every process that I did usi...

cos(2y)= (cos(y))^2 - (sin(y))^2 identitynow consider identity (cos(y))^2+(sin(y))^2=1by rearranging this to (cos(y))^2 - 1 = - (sin(y))^2 we can now substitute it into our first identity to obtaincos(2y)...

This is an equation laid out in terms of the natural logarithm, which essentially is the reverse function of e^x . From this equation we need to find a solution for x =? Since we know that this ...

Earthquakes are caused by the breakage of underground, crustal rock largely close to or near plate boundaries. It should also be noted that the breakage of rock occurs along a fault line, which is a long ...
