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-5cosx`, 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 `-5 cos x`, use the derivative of cosine, remembering to include the chain rule for the coefficient `-5`.
Be sure your variables match those in the question `-13+5 sin x`
