I have read everything you have provided carefully and here is my conclusion. y = -\ln|-2\cos 3x + 3| does not satisfy the differential...

By the way, cogito, in modular arithmetic, 1 full turn = n full turns i.e. 0 = 2 \mod 1 Maybe someone should tell Mr. Howard that 2...

Perhaps, in terms of multiclause functions f(x) = \begin {cases} x^2 \text{ if } x \ne 1 \\ 2 \text{ if } x = 1 \end {cases}

Almost. \lim_{n\rightarrow \infty}\left(1+\frac{1}{n^2}\right)^n = 1. And we can certainly define 1^\infty :=\lim_{n \to \infty} 1^n =...

Could someone please help? best 6 papers turned in by 28 classes are re-read by organizers to ensure marking is correct.

Gracias, muchas, your guidance is much appreciated. \frac{2 \times 4 \times ^4P_4}{^6P_6} = \frac{192}{720} = 0.2\overline 6

Read the problem carefully: The other 22 papers are somewhere else; they don't come into the problem at all. They can't be in the stack.

Small correction: I omitted the absolute value on the right, which doesn't affect the result.

Your check is incorrect. If y = -ln|-2cosx+3|, then y(0) = -ln|-2cos(0)+3| = -ln|-2+3| = -ln(1) = 0. So the error is not that it...

Check those final lines: \displaystyle \ln\left|\frac{dy}{dx}\right| = \ln|6\sin 3x| + y \displaystyle \frac{dy}{dx} = 6\sin 3x \ e^y...
