Verify the identity. $$ \frac{\cot^2 t}{\csc t} = \cot t \cos t $$ Which of the following four statements establishes the identity? A. $$ \frac{\cot^2 t}{\csc t} = \cot t \left( \frac{\sin t}{\cos t} \right) (\sin t) = \cot t \cos t $$ B. $$ \frac{\cot^2 t}{\csc t} = \cot t \left( \frac{\cos t}{\sin t} \right) (\sin t) = \cot t \cos t $$ C. $$ \frac{\cot^2 t}{\csc t} = \cot t \left( \frac{\cos t}{\sin t} \right) \left( \frac{\cos t}{1} \right) = \cot t \cos t $$ D. $$ \frac{\cot^2 t}{\csc t} = \cot t \left( \frac{\sin t}{\cos t} \right) \left( \frac{\cos t}{1} \right) = \cot t \cos t $$

Use the Laplace transform to solve the system. x' + y = t x + y' = 0 x(0) = 3, y(0) = 3 x = -\frac{1}{4} + \frac{11}{8}e^{-2t} - \frac{1}{8}e^{2t} y = t + \frac{11}{4}e^{-3t} + \frac{1}{4}e^{2t}
