This article uses the  Trigonometric Identities. Sum and Difference Formulas sin (x + y) = sinxcosy + cosxsiny sin (x − y) = sinxcosy − cosxsiny cos (x + y) = cosxcosy − sinxsiny. 25 Feb 2019 Note that cos(2x)=1−2sin2x. From here you get −14cos(2x)+C=−14+12sin2x+ C=12sin2x+C1. where C1=−14+C is a new constant.
