When you create an Easy Setup Key, the autorun.ini file on many flash drives is overwritten with the Linksys Wi-Fi Router or Linksys X-series Gateway program and settings. The autorun.ini file has instructions that tell your computer what programs to launch automatically.
The Discriminant. In the quadratic formula, the expression under the square root sign, b 2 â 4 ac, is called the discriminant. The sign of the discriminant can be used to find the number of solutions of the corresponding quadratic equation, ax 2 + bx + c = 0.If the discriminant b 2 â 4 ac is negative, then there are no real solutions of the equation.f the discriminant is positive, then the Â± symbol means you get two answers. The solutions of this equation correspond to the x-intercepts of the parabola. y = ax 2 + bx + c. So, you can also use the discriminant to find the number of x-intercepts of a parabola.
The slope of the tangent line is equal to the derivative of the function at the marked point. The derivative of a function of a real variable measures the sensitivity to change of the function value with respect to a change in its argument (input value). Derivatives are a fundamental tool of calculus. For example, the derivative of the position of a moving object with respect to time is the object's velocity: this measures how quickly the position of the object changes when time advances.
