d/dx of lnx is 1/x Therefore the derivative is 1/(1+x)
Derivative of x = 1, and since sqrt(x) = x^(1/2), derivative of x^(1/2) = (1/2)*(x^(-1/2))Add these two terms together and derivative = 1 + 1/(2*sqrt(x))
x= (x+1)/x(x+1)/x -x = 0f'(x) = ((x*1)-(x+1)) /x^2 -11/x^2 - 1
1 divided by x to the third power equals x to the negative third. The derivative of x to the negative third is minus three x to the negative fourth.
(-x+tanx)'=-1+(1/cos2x)
