Derivada de sin(9x)*cos(9x)

Answer

-9 \cdot \mathrm{sin}\left(9 \cdot x\right)^{2}+9 \cdot \mathrm{cos}\left(9 \cdot x\right)^{2}

Derivative of sin(9x)*cos(9x)

Rule Used: Product Rule
Steps: Identify a product of two functions of x in $\sin(9 \cdot x)$ * $\cos(9 \cdot x)$ : 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: - $9 \cdot s$ in( $9 \cdot x$ )^2+ $9 \cdot c$ os( $9 \cdot x$ )^2

A derivada de sin(9*x)*cos(9*x) é -9*sin(9*x)^2+9*cos(9*x)^2.
