Knowing exact uops would not be beneficial, what you can find is how many uops per instruction in Optimization Manual.

Answering an old question:)

For example such a complex instruction like fsin could be decoded into a few uops.Like load/store of argument/result from/to memory , internal accumulation of the result to register file and uops to work with floating point adder and multiplier unit.It could be also pipelined at adder/multiplier stage.
