cos2x+√3+12sinx−√34−1=0 that lie in the interval (−π,π), we will follow these steps: Step 1: Rewrite the equationStart by rewriting cos2x in terms of sinx:cos2x=1−sin2xSubstituting this into the equation gives:1−sin2x+√3+12sinx−√34−1=0 Step 2: Simplify...
Using the product-to-sum formula again for sinxsin3x:sinxsin3x=12(cos(2x)−cos(4x))Now we can substitute this back:12∫(1−cos(6x)2−12(cos(2x)−cos(4x)))dx Step 6: Combine and IntegrateCombining the terms gives:14∫(1−cos(6x)−cos(2x)+cos(4x))dxNow we can ...
