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...
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 ...
Alternatively, you can add this formula using the Formulas tab in the uppermost ribbon of your Excel sheet. Go to “Formulas”> “Math & Trig”> “PRODUCT”> Enter. ADVERTISEMENT Step 2:Provide an argument for the PRODUCT function. In this case, you want the product/multiplication of number...
6. The compositions of claim 1 wherein the solid, polymorphic, unsubstituted triglyceride gellant comprises a solid triglyercide corresponding to the formula: ##STR4## wherein R1, R2 and R3 are independently selected from saturated alkyl groups having from about 2 to about 30 carbon atoms, ...
