[Sofia_S]

"Prove that in a triangle it is in effect sinA/a=sinB/b=sinC/c

Please help me...

Sofia: In order to receive help you must show that you have attempted this problem. It would also help matters if you would properly state the question.

apmcavoy: I've soft deleted your post. I'll restore it once Sofia completes the problem. We do not offer homework help until an attempt is shown. If a student has no clue on how to start a problem then it would be best to ask some guiding questions. And under no circumstances should a complete solution be offered.

You both agreed to these rules, which I will reproduce here for your review:

Homework Help:
On posting questions: Any and all high school and undergraduate homework assignments or textbook style exercises for which you are seeking assistance are to be posted in our Science Education Zone. This should be done whether or not the problem is part of one's coursework. The reason for this is that the scientific and mathematical sections of Physics Forums are to be reserved for discussions and not academic assistance. Since graduate level assignments are meant to be more thought provoking (and hence more worthy of discussion), graduate level questions will be allowed in the relevant part of the main section of PF, provided that the graduate student attempts the problem and shows his work. NOTE: You MUST show that you have attempted to answer your question in order to receive help.

On helping with questions: Any and all assistance given to homework assignments or textbook style exercises should be given only after the questioner has shown some effort in solving the problem. If no attempt is made then the questioner should be asked to provide one before any assistance is given. Under no circumstances should complete solutions be provided to a questioner, whether or not an attempt has been made.

What do you mean by "it"?

 

[Erzeon]

does he mean, prove the sine rule for a triangle?

Ok :) You have right... I will return with the exercise.
Thanks :)
