Circle wikipedia maths

A chord of a circle is a straight line segment whose endpoints both lie on a circular arc. If a chord were to be extended infinitely on both directions into a line, the object is a secant line. More generally, a chord is a line segment joining two points on any curve, for instance, an ellipse. A chord that passes through a circle's center point is the circle's diameter. The word chord is from the Latin c… WebThe imaginary unit or unit imaginary number (i) is a solution to the quadratic equation + =.Although there is no real number with this property, i can be used to extend the real numbers to what are called complex numbers, using addition and multiplication.A simple example of the use of i in a complex number is +..
