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=13x+7cosx`, apply the basic rules of differentiation to each term separately. For the linear term `13 x`, the derivative is simply the coefficient `13`. For the trigonometric term `7 cos x`, use the derivative of cosine, remembering to include the chain rule for the coefficient `7`.
Be sure your variables match those in the question `13-7 sin x`
