Find an equation of the line tangent to the curve x = t + \cos t, y = 2 - \sin t at the point where t = \frac{\pi}{6} Find all values of t in (0, \pi), for which the tangent line to the graph of x(t) = t + \cos 2t, y(t) = t - cos 2t, is horizontal...
Method 1 : Since the circle is tangent to both axes, the center of the circle is on the line. shing \(5_1-3_1=8x±y=0. b \(x=4y=4. \(x=1y=-1. Therefore the equation of the cirele is (x -4)+ (y-4)2=16 or(x-1)2+(y+1)2=1. Method 2: Let the equation of ...
