The square describes his world as a plane populated by lines, circles, squares ... That is, for the equations that describe superstring theory to begin to work out—for the equations to connect ...

As the tangent is a straight line, the equation of the tangent ... the value of \(c\) in the equation. Find the equation of the tangent to the circle \(x^2 + y^2 = 25 \) at the point (3, -4).

Soddy's equations for the circle and the sphere to space of n-dimensions, and more recently Mr. C. C. Mason has submitted a verse on similar lines. Prof. Soddy informs us that he received a verse ...

The tangent is perpendicular to the radius which joins the centre of the circle to the point P. As the tangent is a straight line, the equation of the tangent will be of the form \(y = mx + c\).
