Can you solve the problem involving Intersection Chords Theorem?

Two chords AB and CD of a circle intersects perpendicularly at the point P. The length of the segments AP, PB, CP and PD are given. Can you calculate the radius of the circle? Watch the full video for an interesting solution with the help of intersecting chord theorem? Learn something new and different.

Can you solve the system of non-linear equation?

A system of linear equations can be solved easily by many standard methods. Even in high school mathematics courses, students are taught Cramer's rule and the method of Matrix to solve a given set of consistent linear equations up to three variables. More advance methods are taught in the course of linear algebra. But for a given system of non-linear equations, there is no specific method. Different ideas need to be applied across various parts of mathematics to get the solution. Nonetheless using school level mathematics, many interesting problems can be solved. Here we present once such problem, where we have to solve a system of non-linear equation. x^2 -  yz = 3, y^2 - zx = 4 and z^2 - xy = 5 is the system here, we will solve it using elementary ideas. Knowledge of arithmetic progression is essential.

Can You Solve The 5 Circles inside the square Problem?

Five circles with the same radius are placed inside a square, whose sides are not known. The radius of the circle is given. The problem is to find the side of the square. Four circles are placed inside the square at the four corners in such a way that the sides of the square are tangents to the circle. The fifth circle is place between the four circles, such that it touches the four circles externally.
