we will find a missing value of a tangent line given the length of an equivalent tangent line. In the second example, we will find the length of the line from the center of the circle to the point where the tangent lines intersect. Finally, the third example will have us finding the ...
Unit Circle Theunit circleis a circle with a radius equal to 1, centered on the origin (0, 0). It is used to calculate the cosine, sine, and tangent of any angle within the circle, although it is most commonly used for easy memorization of thesineandcosineof angles that are multiples...
Find the equation of the tangent to the circle x^2 + y^2 - 80x - 60y + 2100 = 0 at the point nearest to the origin.

What is the formula of length of tangent? It is observed that |TC| is the radius of the circle, so |TC|2=g2+f2–c. This gives the length of the tangent from the point P(x1,y1) to the circle x2+y2+2gx+2fy+c=0.
Method 1: Since the circle is tangent to both axes, the center of the circle is on the line. 5x-3y=8 Solving \(5x-3y=8x+y=0. \(x=4y=4.[x=1y=-1. Therefore the equation of the ci rcleis(x-4)^2+ (y-4)^2=160r(x-1)^2+(y+1)^2=1 . Method 2: Let the equation ...

Hi, and welcome to this video on tangent! The word tangent has two different meanings in math. In geometry, it is used to denote when an object is touching another object at only one point, like when a line touches a circle at only one point. We’re not concerned with that one today...
