Hi Muhammad,  From the sum of angle formula;  cos(A+B) = cosAcosB - sinAsinB  Letting A = B = θ  cos(2θ) = cosēθ - sinēθ    But we also know the identity; cosēθ + sinēθ =

#### 2016-03-07 O/l problem:

Hi Bob,  We have been given an equation which gives us the relationship between the position of the particle X, as measured from the fixed point O, and the time t.   X = t - 16/t  The problem states that

#### 2015-08-28 Differential Calculus:

Hi Christine,  The first thing we have to do is relate the base angle to the altitude. Consider half of the isosceles triangle to one side and you have a right-angled triangle with a 4 feet long base.

Hi Nicole,  First of all, you need Discrete Maths for computer science so there's no point asking if it's difficult. I mean this in the sense that difficulty is a relative thing and university education
