Problem 1
a) $ \lambda_n^c=\lambda_n^b-\lambda_n^d $
b) $ G_n = \frac{d\lambda_n^c}{dx}=-\mu (x,y_0+n\Delta d)\lambda_n^c $
c) $ \lambda_n = \lambda_n^c e^{-\int_{0}^{x}\mu(t)dt} \Longrightarrow \hat{P}_n = \int_{0}^{x}\mu(t)dt= -ln(\frac{\lambda_n}{\lambda_n^c}) = -ln(\frac{\lambda_n}{\lambda_n^b-\lambda_n^d})<\math> d) <math>\hat{P}_n = \int_{0}^{T_n}\mu_0dt = \mu_0 T_n<\math> A straight line with slope <math>\mu_0<\math> <math><\math> ==Problem 2== a)Since U is $p \times N$, $\Sigma$ and V are $N \times N$\\ $
