The degree of a quadratic equation?
The Quadratic Formula song: (my grade saver) To the tune of the jack in the box song X equals negative B plus or minus square root of B squared minus 4AC all over 2A :)
Give a recursive version of the tree-insert?
Insert (Node *root, Node *newp) { if (root->left==NULL) { root->left= newp; return; } if (root->right==NULL) { root->right= newp; return; } Insert (root->left, newp); }
Write a Qbasic program to find the root of a quadratic equation using the formula if the result is less than 0 the program should print the root are immerginary and end the program?
(Uses Square Root Function) PRINT "Ax^2 + Bx + C = 0" INPUT "A = ", A INPUT "B = ", B INPUT "C = ", C D = B * B - 4 * A * C IF D > 0 THEN DS = SQR(D) PRINT "REAL ROOTS:", (-B - D) / (2 * A), (-B + D) / (2 * A) ELSE IF D = 0 THEN PRINT "DUPLICATE ROOT:", (-B) / (2 * A) ELSE DS = SQR(-D) PRINT "COMPLEX CONJUGATE ROOTS:", (-B / (2 * A)); "+/-"; DS / (2 * A); "i" END IF END IF
Is there a relationship between density and stiffness?
the natural frequency of a system involves a equation relating mass and stiffness i.e f=1/2pi root of k/m where f : frequency k :stiffness m:mass mass is nothing but density*volume from the relation density = mass/volume another relation may be from the basic force equation f=-k*x we know f=m*a substuting for f we get m*a=-k*x
Write a program to find the square root of the quadratic equation using flow chart?
You don't need a flow chart for that; just use the quadratic formula directly; most programming languages have a square root function or method. You would only need to do this in many small steps if you use Assembly programming. The formulae would be something like this: x1 = (-b + sqrt(b^2 - 4*a*c)) / (2 * a) and x2 = (-b - sqrt(b^2 - 4*a*c)) / (2 * a) where a, b, and c are the coefficients of the quadratic equation in standard form, and x1 and x2 are the solutions you want.
