WebAnswer: 2 π (or about 6.283 pieces of string). Radians Preferred by Mathematicians Because the radian is based on the pure idea of "the radius being laid along the circumference ", it often gives simple and natural results when used in mathematics. For example, look at the sine function for very small values: WebA circle can have tangents on every point on it. Hence, a circle can have infinitely many tangents ☛ Related Questions: A tangent PQ at a point P of a circle of radius 5 cm …

WebProcess (How to do the activity) The teacher can show the geogebra file. Move the points on circumference and explain secant. When both endpoints of secant meet, it becomes a tangent. Name the points on the circumference of the circle. At how many points is the line touching the circle ? For two circles, there are generally four distinct lines that are tangent to both (bitangent) – if the two circles are outside each other – but in degenerate cases there may be any number between zero and four bitangent lines; these are addressed below. For two of these, the external tangent lines, the circles fall on the same side of the line; for the two others, the internal tangent lines, the circ… charles mackintosh wife

Web2 (g – g’)x + 2 (f – f’)y + (c – c’) = 0. (ii) If the circles touch each other then the above equation gives the common tangent at the point where the circles touch each other. It is also the Radical axis of the two circles. (iii) If the two circles intersect then above equation gives the equation of the common chord. WebThree Common Tangents: If two circles touch each other externally at one point, they will have three common tangents. 5.
