Derivative of sin(7x)+cos(2x)

Answer

−2⋅sin(2⋅x)+7⋅cos(7⋅x)-2 \cdot \mathrm{sin}\left(2 \cdot x\right)+7 \cdot \mathrm{cos}\left(7 \cdot x\right)
-2*sin(2*x)+7*cos(7*x)

Derivative of sin(7x)+cos(2x)

Rule Used
Sum Rule
Steps
  1. Differentiate sin⁡(7⋅x)\sin(7 \cdot x)+cos⁡(2⋅x)\cos(2 \cdot x) term by term. The sum rule says the derivative of a sum is the sum of the derivatives, and the derivative of a constant term is 0, so that term disappears.
  2. Final answer: -2⋅s2 \cdot sin(2⋅x2 \cdot x)+7⋅c7 \cdot cos(7⋅x7 \cdot x)

The derivative of sin(7*x)+cos(2*x) is -2*sin(2*x)+7*cos(7*x).
