Derivative of e^(4x)*cos(3x)

Rule Used
Product Rule
Steps
  1. Identify a product of two functions of x in e4⋅xe^{4 \cdot x}*cos⁡(3⋅x)\cos(3 \cdot x): use the product rule (uv)' = u'v + uv'. Each factor is differentiated once while the other is held as-is, then the two terms are added.
  2. Differentiate each factor and combine.
  3. Final answer: -3⋅e4⋅x3 \cdot e^{4 \cdot x}*sin⁡(3⋅x)\sin(3 \cdot x)+4⋅e4⋅x4 \cdot e^{4 \cdot x}*cos⁡(3⋅x)\cos(3 \cdot x)

The derivative of e^(4*x)*cos(3*x) is -3*e^(4*x)*sin(3*x)+4*e^(4*x)*cos(3*x).
