WebMath Calculus 11.Show that if a11, a12, a21, and a22 are constants with a12 and a21 not both zero, and if the functions g1 and g2 are differentiable, then the initial value problem x′1=a11x1+a12x2+g1 (t),x1 (0)=x01x′2=a21x1+a22x2+g2 (t),x2 (0)=x02 can be transformed into an initial value problem for a single second-order equation. WebSep 7, 2024 · GCD of the already GCD (2 answers) Closed 5 years ago. Let d = gcd ( a, b). If a = d a ′ and b = d b ′, show that gcd ( a ′, b ′) = 1. So far I concluded that d divides both a and b, and their remainders are zero. I don't know what to do next, someone please help me. Thank you. abstract-algebra elementary-number-theory Share Cite Follow
