The equation of the tangent to the circle x^2+y^2=a^2, which makes a triangle of area a^2 with the coordinate axes, is (a) x+-y=asqrt(2) (b) x+-y=+-asqrt(2)
Determine whether the statement, the slope of the tangent to f(x) = the square root of (1 2x) at (- 4, 3) is -2/3, is true or false. At the point of tangency, the function's value and the local linear approximation of a function ...
Find the coordinates of the point on the curve y2=3−4x where tangent is parallel to the line 2x+y−2=0 . View Solution Let P be the point on the parabola y2=4x which is at the shortest distance from the center S of the circle x2+y2−4x−16y+64=0. Let Q be the po...
Circle is the set of points in a plane that are equidistant from a given point. Learn more about circle, tangent equation, chord etc. with the help of solved examples.
12K A tangent of a circle is a line that touches the circle at exactly one point. Learn how to construct a tangent of a circle passing through a point on a circle, passing through a point outside a circle, or touching two circles. Related...
Why is the locus of the centres of the circles passing through two points is the perpendicular bisector of the two points? 4 Finding circle with two points on it and a tangent from one of the points 0 Two chords in a circle cut each other up into equal line segments. What...

Write the equations of the following circles (Textbook P77, exercise 1) (1) the center of the circle is at the origin, and the radius is 3; (2) the center of the circle is, and the radius is (3) after the point, the center of the circle is at the point 2. Write the center ...
If the point p is outside the curve Q, the quadric R will be an “intersecting lines” quadric consisting of the two tangents to the curve. If the point p is on the curve Q, then pQpT is zero and R is just l· lT, the coincident-line quadric that is the tangent line l coinci...
