Question

calculati [tex] \int\limits {e^x} \, dx

\int\limits {a^x} \, dx

\int\limits {x} \, dx


Calculati:

a)\widehat{2}+x=\widehat{5}


b)\widehat{t}+\widehat{7}=\widehat{5}


Aceste ecuatii sunt in ZI 4 ,dau coroana[/tex]

Answer 1

Integralele acestea se rezolva cu ajutorul formulelor directe

[tex] \int\limits {e^x} \, dx =e^x+C [/tex]

$\int\limits {a^x} \, dx = \frac{a^x}{ln a}+C$

$\int\limits {x} \, dx= \frac{x^2}{2}+C$


Exercitiul 2

a) [tex]\widehat{2}+x=\widehat{5} x=\widehat{5}-\widehat{2}=\widehat{3}[/tex]

b) [tex]t+\widehat{7}=\widehat{5} t=\widehat{5}-\widehat{7} t=\widehat{-2} t=\widehat{2}[/tex]
