EBK DIFFERENTIAL EQUATIONS AND LINEAR A
- Consider the system of linear equations in x and y. ax+by=ecx+dy=f Under what conditions will the system have exactly one solution?arrow_forwardFor Exercise 1-8, solve the system of differential equations. dx1dt=x1+6x2 dx2dt=5x1+2x2arrow_forwardConsider the following system of equations in R2→R? y + 2x + x – yıy2 = 15 2y + xỉ + x + yıY2 = 38 What is the value of y, and y2 if x1 = 1 and x2 : = -1 By using derivative, calculate the new value of y, and y2 when x1 reducesarrow_forward
- Are the functions f, g, and h given below linearly independent? f(x) = e2" + cos(7x), g(æ)= e2 – cos(7x), h(x) = cos(7x). If they are independent, enter all zeroes. If they are not linearly independent, find a nontrivial solution to the equation below. Be sure you can justify your answer. (e2z + cos(7x)) + (e2z – cos(7x)) + (cos(7x)) = 0. help (numbers)arrow_forwardWrite the given system as a set of scalar equations. Let x' = col (x1'(), x2 (1), x3'(1)- 0 10 1 2 x' = 0 0 1 x+t - 1 1 -11 4 .... X1 (t) = x2'(t) = X3 (t) =arrow_forwardSolve the given (matrix) linear system: X' [1 2] X [3 4arrow_forward
- Q3. (a) Find the root of f (x) = x2 -2x - 2,correct 3 dp, using Newton-Raphsonmethod.(b) Find the inverse of the given matrix using Choleski’s method, A= [4 6 8, 6 10 17, 4 17 25] Hence, solve the following system of equations: 4x1+6x2+8x3=6 6x1+10x2+17x3=5 8x1+17x2+25x3=7arrow_forwardFind general solutions to the linear system. Use the method of polynomial differential operators, finding the determinant and roots, and then substituting in the original first equation to eliminate extra coefficients. x′=−x+3y,y′=2yarrow_forward
