English: .
. Let C be the curve consisting of all ordered pairs (f(t),g(t)), with : f : t-> a*sin(k1*t) g : t-> b*cos(k2*t) With t = 0.785, the equation of the tangent is : y = ((Dg/Dy)(t))(x-f(t))+g(t) = 0.500*x +1.414 Find PB, the length of the tangent from P to the y axis. P( 1.414, 2.121) P(f(t), g(t)) B(+0.000, 1.414) B(0, g(t)-f(t)*DgDf(t)) PB = sqrt(f(t)**2*(1+DgDf(t)**2)) = 1.581 To see the graph, open the file "a_main.plt" with Gnuplot.
