anyone can help me to plot a point.(adsbygoogle = window.adsbygoogle || []).push({});

what i am doing is i use FindMaximum first to know the point of maximum.Code (Text):r = Plot[Sin[j], {j, 0, Pi}];

then i manually key in the x,y coordinate from the search.Code (Text):FindMaximum[Sin[j], {j, Pi}]

is there any way i can plot the maximum point without key-in manually using the findmaximum point.Code (Text):onedot = ListPlot[{{1.5707963267948966, 1}},

PlotStyle -> {Hue[0.67], AbsolutePointSize[7]}];

Show[r, onedot]

thanks
