**Find equations of both the tangent lines to the ellipse x2**

I wonder if one can draw tangent lines out of a point to a path of an ellipse using tikz. Actually for the case of circle paths this can be accomplished easily as given in the tikz-pgf manual, but for other paths it wouldn't be an easy task.... I need to plot a tangent line to an ellipse defined by generic ellipse characteristics center (xCenter, yCenter), major axis aR, minor axis bR, and angle of tilt th. I am currently using the code below to do this, which is based off of equations from: here . when I try to plotted with a rotated ellipse it is not robust and comes out whacky - especially when the tilt is bigger.

4/12/2006Â Â· The problem statement, all variables and given/known data The problem is Find the equation of the line with a positive slope that is tangent to the ellipse (x^2)/9 + (y^2)/4 = 1 At x=2 2. Relevant equations Now I know that to find the tangent, I find the derivative of the equation. So I......

10.The ellipse x 2 4 + y 16 = 1, oriented counter-clockwise. 8 <: x= 2cost y= 4sint 0 t 2Ë‡ For problems 11-13, nd dy dx and d2y dx2 at the given point without eliminating the... Find the equation of the tangent line to the ellipse at the given point The equation for the tangent line can be found using the formula for a line when the slope and one point are known. (y - n) = slope ( x - m) = -(m/n) (b 2 /a 2) ( x - m) After a lot of algebra, this can be reorganized into the form: a 2 n y/(a 2 n 2 + b 2 m 2) + b 2 m x /(a 2 n 2 + b 2 m 2) = 1 . This is the equation

### 7/10/2010Â Â· For the best answers, search on this site https://shorturl.im/axycP You didn't provide the form of the equation for the ellipse nor the value of the slope, so I will assume the form of the equation for the ellipse is xÂ²/aÂ² + yÂ²/bÂ² = 1 where aÂ² and bÂ² are known, and that the slope of the tangent line is m and is also known.

- 28/07/2009Â Â· I guess what you do is sort of like above, but once you find the equation of the tangent line, solve for where it intersects with the ellipse, that way you can find the equation of the line normal at the intersection point.
- Given your two equations, and the parameter [math]\alpha,[/math] you can solve for [math]\beta=0[/math] to find the two values of [math]\alpha[/math] giving the two degenerate equations. Factoring those gives you the four equations of the common tangents.

- 16/10/2012Â Â· " Find the equation of both tangent lines to the ellipse x^2 + 4y^2 = 36 that passes through the point (12,3)." I don't quite no where to start. I've done problems where we had to find the equation of a tangent line at a point, but in this problem the point does not seem to be on the Ellipse.
