5. Use a substitution and an integration by parts to find each of the following indef- inite integrals: (b) | (cos(a) sin(a) esas) de (a) / ( (32 – 7) sin(5x + 2)) de (c) / (e* cos(e=)) dt (d) dr 6. Spot the error in the following calculation: S() will use integration by parts with 1 We wish to compute dr. For this dv du 1 dar = 1. This gives us dr by parts we find dr =...
Prove that sinhx =( e^x - e^-x/ 2), coshx = (ex+e^-x/2) is equal to: sinh x= x+x^3/3! + x^5/5! ... and cosh x= 1+ x^2/2! +x^4/4! .. USE THIS EQUATION: e^x = sum x^n/ n! = 1+x+(x^2/2!) +(x^3/3! )
Please show all work for Number 2. Thank you. ) Solve the nonhomogeneous system: (t) 5 -2 x(sinh(t) 7.jk(t)-| cosh(t)) 20 An interesting application that leads to a system of differential equations is the study of an arms race. The presentation given here is often called the Richardson model, since it was first proposed by the English metcorologist L.E Richardson. We wish to consider the problem of two countries with expenditures for armaments, x and y, measured in billions of...
