[DIMASTROGIOVANNI LUCIANO]

I have a little probleme
maybe two

the first is that I'm not so clever using Latex 

The second is that I like to insert the equations in my 
tesis in the following way of numbering:

equ_1      1.1.a
equ_2      1.1.b
equ_3      1.1.c
equ_4      1.1.d
equ_5      1.1.e

In this moment with the command subequations and using the 
ansmath package I am able to write in this way

equ_1      1.1a
equ_2      1.1b
equ_3      1.1c
equ_4      1.1d
equ_5      1.1e

Can you help me?

Thanks a lot in advance

Best regards

Luciano
