Question

hallar la derivada de : 4cosx +x In x b) In 3x∧3

Answer 1

Explicación paso a paso:

a) y=4cosx +x In x

$y' = 4( - senx) + (1)lnx + x \frac{1}{x} \\ y' = - 4senx + lnx + 1$

b) In 3x∧3

$b) \: y' = In 3 {x}^{3} \\ y' = \frac{3 \times 3 {x}^{3 - 1} }{3 {x}^{3}} \\ y' = \frac{9 {x}^{2} }{3 {x}^{3} } \\ y' = \frac{3}{x}$
