Please show all steps!!!!
1. Let Q1=y(1.1),Q2=y(1.2),Q3=y(1.3), where y=y(x) solves y′′+
(−3.75)y′+(3.125)y= 0, y(0) = 1.5, y′(0) =−0.625
2. Let Q1=y(1.1),Q2=y(1.2),Q3=y(1.3), where y=y(x) solves y′′+
(−3.75)y′+(3.125)y= 114e−3.5x, y(0) = 5.5, y′(0) =−14.625.
3. Let Q1=y(1.1),Q2=y(1.2),Q3=y(1.3), where y=y(x) solves y′′+
(−3.75)y′+(3.125)y=−5e1.25x, y(0) = 1.5, y′(0) = 3.375
For all of the above Let Q= ln(3 +|Q1|+ 2|Q2|+ 3|Q3|). Then T= 5
sin2(100Q)
