Derivative of xsinx + cosx
WebMar 18, 2005 · Will be thankful to yours bit of help. Ok, here is the solution. At first you take the derivative: -> y' = 2x - xcosx. We set y'= 0 to find the critical number y' = 0 when x (2-cosx) = 0. Since: -1< cosx< 1 -> 2-cosx > 0 with all x. -> y' = 0 when x = 0 , and x = 0 is the only one critical number. At x = 0, function y has relative minimum: y ... WebArguably easiest way would be to use the sin 2 x = 2 sin x cos x identity before taking derivatives: ( x sin x cos x) ′ = 1 2 ( x sin 2 x) ′ = 1 2 ( ( x) ′ sin 2 x + x ( sin 2 x) ′) = 1 2 …
