doesn’t this formula help? cos(a-b)=cos(a)cos(b) +sin(a)sin(b)

not really :P

I also have a problem:

My child uses around 23 nappys per week.
I have 5 different models in the supermarket (a, b, c, d, e). Each one differs 0,01 from the others (the price is for each nappy, not for the whole box). The content of the different boxes are also different: 32, 32, 34, 40, 42.
Assuming that my child will have a bigger shit in an exponential number of 0.002 grams per month and that i’ll forget to feed her at least 1 night per week…

Which model’ll be cheaper thinking in a correlative period of two years?

LOL this is real example of applied math :D

This is sum of two periodic functions(signals), I think I can solve i, should not be so hard, I can write you solution, but I’m not sure that your professor will accept it, because this requires some techniques that you probably should not know. What you study? Do you know what is euler’s formula, low of cosines and phasor diagrams?

Also I think that solution should be with

I^2=a1² + a2² + 2·a1·a2·cos( p2-p1 ) ;

or

I=sqrt(a1² + a2² + 2·a1·a2·cos( p2-p1 ));

check if that’s right.

regards

This is so not fair! We are promoting flash here, success of this marketplace is in their interest too. I really don’t get it.

Now we have name ActiveDen… reminds me on some kind of a laundry detergent. :S
