integral of (7^x+1sin(10x)+3sec^2(x))

Lösung

\int (7^{x} + 1 sin (10 x) + 3 sec^{2} (x)) d x

\frac{7 ^{x}}{ln ( 7 )} - \frac{1}{10} cos (10 x) + 3 tan (x) + C

Schritte zur Lösung

\int 7^{x} + 1 \cdot sin (10 x) + 3 sec^{2} (x) d x

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int 7^{x} d x + \int 1 \cdot sin (10 x) d x + \int 3 sec^{2} (x) d x

\int 7^{x} d x = \frac{7 ^{x}}{ln ( 7 )}

\int 1 \cdot sin (10 x) d x = - \frac{1}{10} cos (10 x)

\int 3 sec^{2} (x) d x = 3 tan (x)

= \frac{7 ^{x}}{ln ( 7 )} - \frac{1}{10} cos (10 x) + 3 tan (x)

Füge eine Konstante zur Lösung hinzu

= \frac{7 ^{x}}{ln ( 7 )} - \frac{1}{10} cos (10 x) + 3 tan (x) + C

\int \frac{x + 1}{( x - 1 ) ^{2} ( x ^{2} + 1 )} d x

\int x^{2} a^{2} + x^{2} d x

\int \frac{1}{1 - 16 y ^{2}} d y

\int e^{2 y} (4 - e^{2 y})^{\frac{4}{3}} d y

\int (e^{y^{2}} y) d y
