i am trying to find where exactly is all the Analog pins from digital side.

i can send PWM to pin 44 , 46  does anybody  know the other analog pins?

You don't send PWM to analog pins. You can use the inappropriately named analogWrite to PWM any pin with a ~ in front of the number printed on the board. On the Mega, that is pins 0 to 13 on the digital side.

Could you please explain to me how to talk to those 15pins?
thanks paul

Nicely, very nicely. Use a calming tone of voice.

Or, perhaps the analogWrite() function I mentioned earlier.

You would need to look at the specification for your particular Arduino to know how many pwm-capable outputs it provided,and which physical pins these outputs were connected to. Often the pwm-capable outputs are identified with a '~' label on the PCB, but that's down to the individual PCB designer and not universal.
