Try another version of this question Find `dy/dx` for `y=10x-cosx`. `d/dx(10x-cosx)=`
Get help: Box 1: Enter your answer as an expression. Example: 3x^2+1, x/5, (a+b)/c
To find the derivative `dy/dx` of the function `y=10x-cosx`, apply the basic rules of differentiation to each term separately. For the linear term `10 x`, the derivative is simply the coefficient `10`. For the trigonometric term `-1 cos x`, use the derivative of cosine, remembering to include the chain rule for the coefficient `-1`.
Be sure your variables match those in the question `10+1 sin x`
