Pls help! due tonight!!

try m Sin[x] + n Cos[x] + p /. replacerule (* p + Sqrt[m^2 + n^2] Sin[x + ArcTan[m, n]] *) ... There are two or three tricks that we can use to solve for {a, b, c, ω} . First ... take the second derivative and evaluate both equatinos at x=0 and at x=π. ... Sin[b] -> σ, {ρ, σ}]; eq2 // Column Reduce[eq2, ω] (* { c n == n p, c ω^2 == p ω^2, n (-1 + ...
