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

Answer

-\frac{3 \cdot 325368125^{3 \cdot x} \cdot \mathrm{sin}\left(3 \cdot x\right)}{119696244^{3 \cdot x}}+\frac{3 \cdot 325368125^{3 \cdot x} \cdot \mathrm{cos}\left(3 \cdot x\right)}{119696244^{3 \cdot x}}

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

Rule Used: Product Rule
Steps: Identify a product of two functions of x in $e^{3 \cdot x}$ * $\cos(3 \cdot x)$ : 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.
Differentiate each factor and combine.
Final answer: - $3 \cdot e^{3 \cdot x}$ * $\sin(3 \cdot x)$ + $3 \cdot e^{3 \cdot x}$ * $\cos(3 \cdot x)$

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