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

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!

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!

Here is the Mariusz's plot from 0 to 2Pi with the point.
