How can I add label for every function in plot?

Question

I wrote the following code:

Plot[{Sin[x], Cos[x]}, {x, 0, 10}, PlotStyle -> {Red, {Blue, Thick}}, PlotLegends -> "Expressions"]

I want to have label for every function in plot. Please see the following picture:

Plot[{Sin[x], Cos[x]}, {x, 0, 10}, PlotStyle -> {Red, {Blue, Thick}}, PlotLabels -> Placed["Expressions", Below]] — corey979, Nov 30 '16 at 12:22

Then go basic. Plot[{Sin[x], Cos[x]}, {x, 0, 10}, PlotStyle -> {Red, {Blue, Thick}}, Epilog -> {Text["sin(x)", {3/2 Pi, -1.1}], Text["cos(x)", {Pi, -1.1}]}, PlotRange -> {-1.2, 1.2}] — Feyre, Nov 30 '16 at 12:59

Edit to add Labeled details

You can use Callout for 'in-plot' labels, for example:

Plot[{
  Callout[Sin[x], "Sin[x]", Below], 
  Callout[Cos[x], "Cos[x]", Below]
}, 
{x, 0, 10}, 
PlotStyle -> {Red, {Blue, Thick}}
]

Alternatively if you do not have version 11 you can use Labeled to get a similar effect, like this:

Plot[{
  Labeled[Sin[x], "Sin[x]", Below], 
  Labeled[Cos[x], "Cos[x]", Below]
}, 
{x, 0, 10}, 
PlotStyle -> {Red, {Blue, Thick}}
]

This does lose the lines but you could make a labeling function to customise this, for example:

plotLabel[text_] := Graphics[{
  Line[{{0, -1}, {0, 0}}], 
  Text[Style[text, 10], {0, -2}]
},
ImageSize -> 30
]

Which with Labeled makes:

My Mathematica version is 10. With this code I do not have any output. – user37694 Nov 30 '16 at 12:19
Callout is a new function in version 11. In version 10 you can use Labeled in its place to get a similar output, but it won't give you the lines from the text to the plot line. You could construct your own label creation function with Graphics if you had a specific style in mind. – lowriniak Nov 30 '16 at 13:45
Callout is a new function in Mathematica 11.0 – matmma Nov 30 '16 at 12:50
I've got 10.4 and it don't work using Placed. But it does work using Labeled. Thank you. Tony Dee – Antony DeGance May 25 '17 at 21:07
