The tangent to the point on the circle, where theta is 2 degrees, was found, by working out the gradient, formed by the
neighbouring two points, on the circle. Then, the coordinates, where theta was two degrees, was fed into y = mx + c, to
find c. Then, a line was plotted, from m (the gradient) and c (the intercept).
