Differential equation:
Equation y''+6y'+9y=2xe^(-3x)
Equation y''+49y=14sin7x=7cos7x-98e^7x
Equation xy'=y+2xe-(y/x)
Equation x^2*dy/dx+2xy=3x^2
Identical expressions
y''+4y=t^ two +3e^t
y two strokes of the second (2nd) order plus 4y equally t squared plus 3e to the power of t
y two strokes of the second (2nd) order plus 4y equally t to the power of two plus 3e to the power of t
y''+4y=t2+3et
y''+4y=t²+3e^t
y''+4y=t to the power of 2+3e to the power of t
Similar expressions
