If the equation in x,$$ x ^ { 2 } + m x + n = 0 $$, has two equal real roots, then a pair of real values of m and n that satisfies the condition could be m=___ and n=___. 相关知识点: 试题来源: 解析 2 1 (can be any values of m and n as long as they satisfy...
By plotting, it is seen that y(x) has four real roots between the points (− 0.9,−0.8), (− 0.4, − 0.3) , (0.3,0.4) and (0.8,0.9). The location of root can be further improved by refining the grid near the location of roots. Once the root has been located approximatel...

For the first equation 3x2+kx+3=0, we need to determine the conditions for it to have distinct real roots. The condition for a quadratic equation ax2+bx+c=0 to have distinct real roots is that the discriminant D must be greater than 0:D=b2−4ac>0Here, a=3, b=k, and c=3....
2.4. Thus, the vector origin O and the triad {c1=v1,c2=2b,c3=2a} constitute a Cartesian frame. When ϑ=0 and detR = 1, the three eigenvalues are equal to 1, which implies that R = I3. If detR = 1, we have λ1 = 1 (proper rotation), and if detR = −1, λ1 = ...
