1/y = -3Sin(x)*ln(1+(sin x)^2) + cos(3x) * 1 / 2cos(x)(Sin(x)) eller har jag tänkt fel, tar man allting och lägger det under ett bråksträck? för i så fall blir svaret fel när man ska räkna ut y'(pi/6) om man ignorerar 1/y så blir svaret rätt alltså -3ln(5/4) men om man räknar in 1/y blir det fel.

As we know that: Cos (a+b) = cosa × cosb – sinxa × sinb. Sin (a+b) = sina × cosb + sina × cosb. Now, we will be substituting these formulas into the equation. [cosx × cosy – sinx × siny) × cosy + (sinx × cosy + cosx × siny) × siny.
