Solve for x, between 0 and 360 degrees, 4cos² (x) + 7sin (x) – 2 = 0 The way to approach this problem is to understand th...

(4x + 3)/(x + 1) + 2 = 8

Firstly minus the 2 from both sides

(4x + 3)/(x + 1) = 6

Then multiply both sides by the denominator (x + 1)

4x + 3 = 6(x + 1)

Expand the bracke...

The equation of a circle is (x-a)^2 + (y-b)^2 = r^2, where (a,b) is the centre of the circle, and r is the radius. To condense our equation into this form we have to use the technique of completing the sq...

The aim of this question is to simply outline the main features of the ontological argument. This requires very little analysis. Rather, the point is to clearly and concisely explain the features of the o...

When the interest rate is high in a country it encourages investors to convert their money, e.g. into pounds, and invest their money in the country. The price change can be traced back to basic supply and...
