−cos(c)​⋅(0,1)2. So to find the second derivative of cos^2x, we just need to differentiate -sin(2x) We can use the chain rule to find the derivative of -sin(2x). We can set g(x) = 2x and f(x) = -sin(x). the F(x) = f(g(x)) = -sin(2x). We can then apply the chain rule to find F'(x). The chain rules says that the derivative of F(x) is equal to f’(g(x)).g'(x). f'(g(x)).g'(x) = -cos(2x).2 = -2cos(2x) The second derivative of cos^2x is -2cos(2x) Derivative of cos(2x): (cos(2*x))'-sin(2*x)*(2*x)'-sin(2*x)*((2)'*x+2*(x)')-sin(2*x)*(0*x+2*(x)')-sin(2*x)*(0*x+2*1) 2*(-sin(2*x))-2*sin(2*x) The calculation above is a derivative of the function f (x) First of all y=cos^2x=(cosx)^2 Hence y'=2cosx*(cosx)'=2cosx*(-sinx)=-2cosx*sinx=-sin2x Another way is y=cos^2x=1/2(1+cos2x) Hence y'=1/2*(-sin2x *(2x)')=-sin2x Calculus Science About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Press Copyright Contact us Creators Derivative Calculator d/(dx)(cos^2x) Derivatives.
