Find the Cosine of u + v Find the Cosine of u - v Addition and Subtract of the Tangent function Both are Rational expressions Find the Tangent of u + v Find the Tangent of u + v Find the Tangent of u - v Find the Tangent of u - v Simplify Remember: sin(u-v)=sin u·cos v...
Similarly, the Sum and Difference Formulae are the trigonometric identities that can be used to simplify trigonometric equations or for calculating specific values of trigonometric ratios. Some of these formulae are, sin(A+B)=sinAcosB+cosAsinBsin...
Notice the problem follows a cosine-cosine sine-sine pattern, which makes this either a sum/difference cosine problem. Now that we know which formula to use, we have to make sure the problem is written in the proper form. Looking at the angles, it does not yet exactly fit the pattern...
In the previous chapter, we derived addition formulas from the main Cosine Difference Formula. In this chapter, we will derive many more useful formulas by employing the formulas we have already obtained. As one of the results, for instance, we'll be able to get exact values for trig ...

We use the Sum of 2 Cubes formula given above.64x3 + 125= (4x)3 + (5)3 = (4x + 5)[(4x)2 − (4x)(5) + (5)2] = (4x + 5)(16x2 − 20x + 25)As mentioned above, we cannot factor the expression in the second bracket any further. It looks like it could be ...
It calculates the squared difference of each data point in a data set, and then takes the sum of each of these points. What does the sum of squares tell you? The sum of squares explain the amount of variation in that specific data set. On its own it can't be used to compare to ...
empirical formula n 1.(Chemistry) a chemical formula indicating the proportion of each element present in a molecule:C6H12O6 is the molecular formula of sucrose whereas CH2O is its empirical formula. Comparemolecular formula,structural formula
spatial formula(stereochemical formula) a chemical formula giving the numbers of atoms of each element present in a molecule of a substance, which atom is linked to which, the types of linkages involved, and the relative positions of the atoms in space. ...
Square that difference. Add all the squared values to the running total. Notice how the squaring process in the sum of squares formula ensures that it tends to increase with each additional data point. Negative differences are squared, producing a positive value that adds to the total. Only th...
