4. Use the difference of squares: The numerator simplifies to: sin2Acos2B−cos2Asin2B So we have: sin2Acos2B−cos2Asin2B(sinAcosB+cosAsinB)2 5. Express sinA and sinB in terms of sides of the triangle: Using the Law of Sines, we know: asinA=bsinB=csinC=2R Therefore, we can...
For the Law of Sines, state the formulas, explain them in your own words, and draw a diagram illustrating one of them. Prove that \vec A (\vec A \times \vec B )=0. Show that the following equations either are exact or can be made exact, and so...

Step 4: Use the Law of SinesUsing the Law of Sines, we know that: asinA=bsinB=csinC This gives us relationships between the sides and angles. We can express sinA,sinB,sinC in terms of a,b,c: sinA=a2R,sinB=b2R,sinC=c2R where R is the circumradius of the triangle. Step 5: Substi...
