Q. $\int e^{3x} sin \,2x \,dx $ equals
Integrals
A
$\frac{e^{3x}}{13} (3\, cos\,2x + 2\, cos \,2x) + c$
B
$\frac{e^{3x}}{13} (3\, sin\,2x - 2\, cos \,2x) + c$
C
$\frac{e^{3x}}{13} (-3\, cos\,2x - 2\, cos \,2x) + c$
D
$\frac{e^{3x}}{13} (3\, sin \,2x + 2\, cos \,2x) + c$
Solution:
Correct answer is (b) $\frac{e^{3x}}{13} (3\, sin\,2x - 2\, cos \,2x) + c$
