differentiate (sqrt(1-2x^2)+1)^2?

Question: ive gotten as far as: - 2(sqrt(1-2x^2)+1)(2x) __________________ sqrt(1-2x^2) Best Answers: Answer by EthanLet (1-2x^2) = U and sqrt (U) +1 = R Then by chain rule: (R^2)’ = 2RR’ = 2(sqrt(u) +1)(sqrt(U) +1)’ = 2(sqrt (1-2x^2) +1)((1/2)(1/(sqrt(U)) =(sqrt(1-2x^2) +1)(1/sqrt(1-2x^2) =(1 + 1/sqrt(1-2x^2) Answer by Adrian Sok, you have to use the power rule […] PR News Crimovies
