To set it up very precisely, make the line intersect the circle at only one point so that it can be a tangent line. How do you find the tangent of a circle? The equation for a tangent line to a circle is (x-x0)(x0-h) + (y-y0)(y0-k) = 0, where (x0, y0) is the ...
Recall from geometry that the line draw tangent to a circle is perpendicular to the radius line drawn to the point of tangency.Use this fact to find the equation of the line tangent to the circle x^2 + y^2 = 25 at (-3,4).
Slope of a line tangent to a circle – direct versionA circle of radius 1 centered at the origin consists of all points (x, y) for which x2 + y2 = 1. This equation does not describe a function of x (i.e. it cannot be written in the form y = f(x)). Indeed, any vertical...
