This video goes through 3 examples using the Product to Sum Formulas and the Sum to Product Formulas. The examples are all very basic examples showing a direct substitution into the formula and then simplifying.
MISTAKE: The formula is written incorrectly in the second example. However, the problem has been worked correctly, by using the correct values for the formula that should have been used.

The product to sum formulas are another subset of trigonometric identities. In this video, we use the sum-difference formulas found in this video...
https://youtu.be/In6NZCp4cNA
...to derive the four product to sum formulas:
1. cos(u)cos(v) = [ cos(u - v) + cos(u + v) ] /2
2. sin(u)sin(v) = [ cos(u - v) - cos(u + v) ] / 2
3. sin(u)cos(v) = [ sin(u + v) + sin(u - v) ] / 2
4. sin(v)cos(u) = [ sin(u + v) - sin(u - v) ] / 2
And from these results, we also derive the half-angle (aka power reducing) formulas:
1. cos^2(u) = [1 + cos(2u)] / 2
2. sin^2(u) = [1 - cos(2u)] / 2

Advanced Excel: Master Excel's SUMPRODUCT Formula
This video is part of a series that belongs to my Advanced Training course called "Advanced Excel: Top tips and formulas".
The classical use of Excel's SUMPRODUCT function is to do a sum of multiplications. The good thing about SUMPRODUCT is that it can work on arrays of values and it doesn’t have to be entered as an array function so no need to do control + shift + enter (CSE).
The great thing about SUMPRODUCT, is that it can help solve many more problems in non-obvious ways. It can act as a conditional SUMIFS function or work as a lookup function as INDEX and MATCH does. It can also act as a COUNTIF function.
SUMPRODUCT is also a better SUMIFS, because it can check for OR conditions - which the SUMIFS can't. SUMIFS can only check for AND conditions.
In this video you will see different examples of the SUMPRODUCT function and you will learn how it can save you from unnecessary "workarounds" in your Excel files. It will also show you the SUMPRODUCT formula in slow motion.

Learn how to use the the SUMPRODUCT formula of MS Excel in Hindi. It is Excel’s Magical Functions Here you can learn to calculate the sum of the products of corresponding ranges or cell in MS Excel. shown 2 ways of using the SUMPRODUCT function in MS excel. The purpose of the SUMPRODUCT function is to multiply, then sum, arrays. If only one array is supplied, SUMPRODUCT will simply sum the items in the array. Up to 30 arrays can be supplied.
The purpose of the SUMPRODUCT function is to multiply, then sum, arrays. If only one array is supplied, SUMPRODUCT will simply sum the items in the array. Up to 30 arrays can be supplied.
SUMPRODUCT is an amazingly versatile function with many uses. Because it will handle arrays gracefully and without complaint, you can use it to process ranges of cells in clever, elegant ways.

Learn how to evaluate the cosine of an angle in radians using the sum/difference formulas. To do this, we first express the given angle as a sum or a difference of two (easy to evaluate) angles, then we use the unit circle and the Pythagoras theorem to identify the angles and obtain all the needed trigonometric function values of the angles. When we know the trigonometric function values of the two angles to be added or subtracted, we can apply the sum and difference formulas to evaluate the cosine of the given angle.
