I'm having trouble locating a point of a graph for example my question is plot f(x) = sinx which I was able to do but the next question is find f(Pi/ 6) which I am having trouble finding this point on the graph using mathematica. Please help
Here is the Mariusz's plot from 0 to 2Pi with the point.
Use Plot and Epilog:
f[x_] := Sin[x]; Plot[f[x], {x, 0, Pi/4}, Epilog -> {PointSize[Medium], Point[{Pi/6, f[Pi/6]}]}]
Have fun!
The point is:
pt={Pi/6,f[Pi/6]}
It can be plotted with:
Point[pt]
Or probably:
Graphics[Point[pt]]
Thank you so much!
