Find the equation of the tangent to the circle \(x^2 + y^2 = 25 \) at the point (3, -4). The tangent will have an equation in the form \(y = mx + c\) so to find the equation you need to find the ...

Mathematicians at Monash University have cracked a centuries-old puzzle dating back to the 17th century, extending Descartes’ ...

Monash University researchers have extended Descartes’ Circle Theorem by finding a general equation for any number of tangent ...

A tangent to a circle at point P is a straight line that touches the circle at P. The tangent is perpendicular to the radius which joins the centre of the circle to the point P. As the tangent is ...
