Derivada de sin(7x)*cos(7x)

Answer

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

Derivative of sin(7x)*cos(7x)

Rule Used: Product Rule
Steps: Identify a product of two functions of x in $\sin(7 \cdot x)$ * $\cos(7 \cdot x)$ : 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: - $7 \cdot s$ in( $7 \cdot x$ )^2+ $7 \cdot c$ os( $7 \cdot x$ )^2

A derivada de sin(7*x)*cos(7*x) é -7*sin(7*x)^2+7*cos(7*x)^2.
