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.

Leila. 2013-11-18. Hej Simon! sin(x) = sqrt(1-cos(x)^2) = tan(x)/sqrt(1+tan(x)^2) = 1/sqrt(1+cot(x)^2) cos(x) = sqrt(1- sin(x)^2) = 1/sqrt(1+tan(x)^2) = cot(x)/sqrt(1+cot(x)^2) tan(x) = sin(x Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals.
