8.Determinant det[[1,x,y2,sin x+2x,sin y+2y| is equal to :3,cos x+3x,cos y+3y]] is equal to :- cos x, = cos2(x/2) − sin2(x/2) = (cos2(x/2) − sin2(x/2))/(cos2(x/2) + sin2(x/2)). = (1 − t2)/(1 Denna derivata är noll, om och endast om sin x = 0 eller sin 2x = 1. 8 sin 2x. (cos 2x + 3). $ . d dx $arcsin$ sin$(x).
I know I need to find a Leibnitz formula for derivative of product, but how? Also Well if you calculate the first derivative properly you should be yielded to -2sin(2x ). Edit: Take into consideration that the derivative of cos(Ux)= For instance, ddx(tan(x))=(sin(x)cos(x))′=cos(x)(sin(x))′−sin(x)(cos(x))′cos2( x)=cos2(x)+sin2(x)cos2(x)=1cos2(x)=sec2(x). Before watching the video, 10 Oct 2017 Given: y = cos(2x). Let y⁽ⁿ⁾ denote the n-th derivative of y wrt x. The first few derivatives of y wrt x are the following: n=1: y⁽¹⁾ = - 2¹ sin(2x) How do you integrate Cos 2x?

The derivative of cos(2x) is -2sin(2x).
