Matrix System

Please solve the attached system (give solution in real form)

Equivalent Systems

Write the given second order equation as its equivalent system of first order equations {see attachment} Use v to represent the "velocity function" Use v and u for the two functions, rather than u(t) and v(t). (The latter confuses webwork. Functions like sin(t) are ok.) Now write the system using matrices {see attachment ...continues

solve diff. eq

(6xy-y^3)dx + (4y+3x^2-3xy^2)dy = 0

DIFF EQ

(x^2 +1)y' + 3xy = 6x

Diff eq.

Solve: (cos x + lny)dx + ((x/y)+ e^y)dy = 0
