These are solutions, I need the codes on Matlab

Please and thank you!

1.3 (a) You are given the following differential equation with the initial condition, v 0)0 dv c dt Multiply both sides by mlc' gives m dv m Define a = ng / c' m dv 2 2 c' di Integrate by separation of variables, dv A table of integrals can be consulted to find that dx 1 -tanh Therefore, the integration yields iv c a m 1.3 (a) You are given the following differential equation with the initial condition, v 0)0 dv c dt Multiply both sides by mlc' gives m dv m Define a = ng / c' m dv 2 2 c' di Integrate by separation of variables, dv A table of integrals can be consulted to find that dx 1 -tanh Therefore, the integration yields iv c a m
