Transcribed Image Text:Activity 3:
The equilibrium equation of an engineering problem is described by the differential equation:
dy
· y tan x = 10 tan x
dx
Determine the general solution of y(x) using two different techniques.
tan x dx = - In(cos x) + C
Activity 4:
By applying Kirchhoff's Voltage Law to a series RL circuit, we obtain the differential equation:
di
4+ 2 i = f(t) , t>0
dt
where i(t) = electrical current in Amperes, and t = time in seconds.
With zero initial condition (i(0) = 0), use Laplace transform to obtain the solutions to the
differential equation, assuming:
(4-a) f(t) = te¬t
(4-b) f(t) = 2 sin 5t ... (for this... evaluate the generated solution in terms of transient and
steady-state regions)
(4-с) f(€) 3D 4 u(t) — 3 и(t — 1)
