- Consider the family of functions uc(x,t) of two variables x,t, indexed by the parameter c,uc(x,y)=ln(x+ct)(cos(ct)cos(x)−sen(ct)sin(x)).Determine the value of the parameter c>0 so that the function uc(x,y) is a solution of the wave equationarrow_forward11) Calculate the Jacobian, J, for the change of variables x = u cos(e) - v sin(e) and y = u sin(0) + v cos(0).arrow_forward- 11) Calculate the Jacobian, J, for the change of variables x = u cos(0) – v sin(0) and yu sin(0) + v cos(0).arrow_forward
- Verify that the function u(x, t) = (r – at)° + (x + at)° satisfies the wave equation uu =arrow_forward2. Suppose that a motion described by the vector valued function (i.e. position function) r(t) has velocity given by r'(t) = v(t) = (5 cos t, 5 sin t, –2) and that r(0.) = (2,1, 1). Find the formula for the position function r(t).arrow_forwardShow that y1(t) = cos(3t) and y2(t) = sin(3t) are linearly independent for all t.arrow_forward
