We have already learned a number of formulas useful for expanding or simplifying trigonometric expressions, but sometimes we may need to express the product of cosine and sine as a sum. We can use the product-to-sum formulas, which express products of trigonometric functions as sums. Let’s...
Use the product to sum identities/formulas in order to find the corresponding sum of a product of sine and cosine functions. After finding the formula which contains the required sum, the formula can be rearranged accordingly to make it easier to use. How do you convert sum to product? The...

So, how I can do this? vlookup the nth&n+1th character and sum up all needed data? But there is several currency, so how can I calculate the product accordingly and use it in the sum?

From the factor graph model we can easily derive recursive formulas for symmetric loss networks. Most importantly, for any loss network we can apply efficient message passing algorithms like the sum-product algorithm to compute the marginal distributions and the blocking probabilities of all call ...
