1. Looks like we need practice having MATLAB do our hard math for us! Use MATLAB to determine all solutions to within at least 3 significant digits. Make sure decimals (not fractions or functions of numbers). a) Use MATLAB to determine all values of x that satisfy x4-2x3 + 4x2-8x-0. b) your answers are Determine all values of x in the interval [0,3] that satisfy e e) Take the derivative of esinx. 10 sin(x2). *fan(e-4x3) with respect to x, and evaluate the derivative for x -1 2. More MATLAB! Use MATLAB to determine all solutions to within at least 3 significant digits. Make sure your answers are decimals (not fractions or functions of numbers). a) Evaluate the definite integral of exp(--))dxfromx=Oto 4. b) Determine the values of x, y, and : that satisfy (x-2)2 x+y+2=0 2x- 3y -3z 7 -x + 5y-2z =-8 cosx c) Integrate the function--( +1 from x-0 tox=2. ATTACH A PRINTOUT OF YOUR CODE TO YOUR HW, AND SAVE YOUR CODE FOR FUTURE REFERENCE! 3. Consider the wavefunction (x) = Ae-1x1/L, where L is a length and A is a normalization constant. One could also write this wavefunction as for x > e Aet forx
