먼소리야? Auxiliary equation 풀면 m=1, m=\frac{-1\pm\sqrt{3}i}{2} 나오니까 y_1=e^x, y_2=e^{-\frac{1}{2}x}\sin{\frac{\sqrt{3}}{2}x}, y_3=e^{-\frac{1}{2}x}\cos{\frac{\sqrt{3}}{2}x}지 - dc App
그...m=\frac{-1\pm\sqrt{3}i}{2} 나오니까 y_1=e^x, y_2=e^{-\frac{1}{2}x}\sin{\frac{\sqrt{3}}{2}x}, y_3=e^{-\frac{1}{2}x}\cos{\frac{\sqrt{3}}{2}x}지 - dc App이게 무슨 소린가요?...
