Here are Sage entries that produce a solution for the above expression: y = function('y',t) de = y + k*diff(y,t) == sin(omega * t) des = desolve(de,[y,t]) Notes: In the above code, omega (ω) is a convenience variable that is equal to 2πf, f = frequency in Hertz...
The ternary operator is available in other programming languages, but the syntax or the order of theoperands (arguments)in Python is distinct from other languages, such as C/C++. Programmers rarely use a conditional expression like the ternary operator, which has the lowest preference among all ...
