- Use Laplace transform to find L{f(t)} f(t) = tsin(t)arrow_forward√3/2 1 √1-x2 arcsinx 1/2 dx = 2arrow_forwardThe evolution of a population of Hippos, R(t), in hundreds, time in years, in an African National Park is given by the equation, dR dt (a) Solve the system exactly for R(t). = R(7 – R); R(0) = 3 2 (b) What happens as the time t → ∞o, i.e. what is the population a long time in the future? (c) Write an Euler scheme and compute until the population levels off (using Excel, Matlab, Octave, LibreCalc or similar). Do it twice, once with At = 0.1 and once with At = 0.05. (d) Plot all of your solutions on the same set of axes and comment.arrow_forward
- find For triangle ABC, with vertices A = (3,-1,2), B = (-5,4,-4) and C = (6, −1, −1), (a) the length of side AB, (b) the equation of the line that passes through A and B, (c) the angle at vertex B, (d) a vector perpendicular to the plane containing the triangle ABC, (e) the area of the triangle ABC. (f) the equation of a plane passing through A, B and C.arrow_forwardShowing all working, use the row reduction method to find the inverse of B, given by 5 -1 B = -3 1 3 1 -3 2arrow_forwardConsider the matrix A, given by +63) A = 1 -3 4 -3 4 5 -105 (a) Find the determinant of the matrix, A. (b) Find all possible solutions, x, to the system Ax = b, where b is the column vector, (1,2, −4).arrow_forward
- If a (1,4,2) and b = (−1, −5,3), find |a|, a + b, 3a - 2b, a b, a x b and b × a. What is the angle between a and b?arrow_forwardShowing all working, find the eigenvalues and corresponding eigenvectors of -3 (a) (27) 6arrow_forwardShowing all working and using row operations determine all solutions to the follow- ing system of equations. 2x + 3y-2z = 8, -2x+y+6z= 12, -x+3y-2z = −4.arrow_forward
