using elimination of arbitrary constant, determine differential equations satisfied by the following functions: y=c1e^t sin 3t + c2 e^t cos 3ta. y" + 2y' - 10y = 0b. y" - 10y' + 2y = 0c. 2y" - y' +... more

hi. I need help with solving these equations please for r, θ and φrcos(0)cos(307.8) = 648cos(φ)cos(θ) + 88cos(28)cos(242)rcos(0)sin(307.8) = 648cos(φ)sin(θ) + 88 cos(28)sin(242)rsin(0) = 648sin(φ)+... more
