Calculating 2 Sine Wave Frequencies from Beats Data

[dwanty]

1. Homework Statement [/b)
i have data from 1 to 300 ms ,for every ms i have value eg(for 1 ms=1.7665849,for 2ms = 0.2345674 and so on till 300 ms) when u draw it,it shows a wave ,which is generated by 2 sine wave and i want to calculate these 2 frequencies of sine waves from the given wave...

See trig identities,

In particular find the trig identity for sin(u) + sin(v) = ..., it is about 3/4 the way down the web page above.
