A tangent to a circle is a line which touches the circle once. That is, it does not pass through the circle, which would mean intersecting it twice. A way to form a tangent is draw any line from the centre point of a circle to its edge. A line on the edge perpendicular (at 90 degrees to) this line will be a tangent.
Any line that enters a circle (and is not a tangent) must cross its boundary twice; once to enter, once to exit. Since a secant is a line segment that joins two different points on a curve, such a line as above is a secant.
tangant of circle intercepts it only on one point. In real the point where tangent meets the circle and intercepts it are same
Draw one square, and draw one circle. Find the center in each, and draw one straight line vertically. Then find the middle once more but this time draw a line straight through horizontally. You have four equal parts in each shape.
A function is not a function if it passes through the vertical line test more than once, and it is not linear or a quadratic.
The vertical line test! Imagine a vertical line going through all points of the graph. As long as the vertical line only touches the graphed line once, it's a function. If it touches more than once, it is not.

You place a ruler on a piece of paper and trace both sides. Put the point of your pair of compasses on the line and draw a circle. Then draw another circle, that is the same size, the same way further along the line. You will then be able to use your rule to draw a line that is a tangent to the two circle, and so parallel to your first line. Once you have done this you will realize that you don't need to draw a full circle just a small arc.
The Antarctic Circle is the line of latitude located in the Southern Hemisphere, approximately 66.5 degrees south. It marks the southernmost point where the sun can be seen at least once a year. The Arctic Circle, on the other hand, is located in the Northern Hemisphere.
Restate question: What is an example of a non-function? The equation of a circle is x2 + y2 = r2. Since a function can only be intersected once by a vertical line, the circle is not a function (almost any vertical line through the circle will cut it twice). If you solve the equation for y, you must write: y = +/- sqrt(r2-x2), so for each value of x there are TWO values of y.
A function is not a function if it passes through the vertical line test more than once, and it is not linear or a quadratic.
