Hey, so very often when I use my calculator to get the answer to a quadratic equation by using the quadratic formula, it says ERROR. Because all parabolas are symmetrical, the x co ordinate of the turning point (along the vertical axis of symmetry) must be the middle point between the two roots. Ti 83 online calculator, comparing integers worksheet, exponential ti89, damper spring under mass, factoring polynomials x cubed. Users can then find the vertex of this parabola by using the “min” or “max” function on the calculator. In this case, b = 0, since there is no b term, and a is 1 (the number before the x squared) : -b/2a = -0/2. To calculate the slope intercept form equation from two coordinates (x 1,y 1) and (x 2,y 2): Step 1: Calculate the slope (y 2 - y 1) / (x 2 - x 1) Step 2: Calculate where the line intersects with the y-axis by entering one of the coordinates into this equation: y - mx = b. When the conic section is given in the general quadratic form + + + + + =, the following formula gives the eccentricity e if the conic section is not a parabola (which has eccentricity equal to 1), not a degenerate hyperbola or degenerate ellipse, and not an imaginary. Not only does this calculate the roots of the equation, it will also show the derivative and the point at which the maximum or minimum exists. Where is a function at a high or low point? Calculus can help! A maximum is a high point and a minimum is a low point: In a smoothly changing function a maximum or minimum is always where the function flattens out (except for a saddle point).
