An autonomous system of two first order differential equations can be written as: A third order explicit Runge-Kutta scheme for an autonomous system of two first order equations is Consider the following second order differential equation, Use the Runge-Kutta scheme to find an approximate solutions of the second order differential equation, at t = 1.2, if the step size h = 0.1. Maintain at least eight decimal digit accuracy throughout all your calculations. You may express your answer as a...

molecular formula is not given
No forma For the IR spectrum, each major signal should be identified by wavenumber (stretching. frequency) and assigned to the corresponding bond. A conclusion about functional groups should also be drawn from the spectrum. In the C-NMR spectrum, the chemical shift of each signal should be noted and a structural assignment should be made. In 'H-NMR spectrum, the chemical shift, integration, and splitting pattern for each signal should be noted and a structural assignment should...

need help drawing the structures for each
For each pair of spectra, first calculate the THD for the molecular formula. Then draw a structure which matches all features of both spectra (there may be more than one structure which fits). For partial credit, write out individual spectral interpretations on each spectrum, noting either presence (or absence) of FG's or bond types. Remember your calculated IHD!! (6 points each) 1.
