How do I get rid of the default spacing at the top of the page, as I want to move all of my text up?

Help!

I want to move all of my text up, but I can't seem to control the spacing before my title. How do I proceed?

My Source code:

    \documentclass[10pt,a4paper]{article}
    \usepackage[utf8]{inputenc}
    \usepackage[T1]{fontenc}
    \usepackage[french]{babel}
    \usepackage{lipsum}
    \usepackage{blindtext}
    \usepackage{amssymb}
    \usepackage{amsmath}

    \begin{document}

    \begin{center}
        \Large
        \textbf{Exercice no.1}
    \end{center}

.................................................................................................................................................................................

    \\
    \\
    \Large{a)}
    \\
    \\
    \Large{$\lambda = 0$}\\ 
    \\
    \Large{$\Rightarrow y''= 0$}\\
    \Large{$\Rightarrow {y=ax+b \quad (a,b\in\mathbb{R}) \quad} \quad 
    \textrm{OU} \quad {y=0}$}\\
    \\
    \Large{Or, une fonction du premier degré est injective et, donc, ne respecte 
    pas les conditions initiales.}\\
    \\
    \Large{d'où $y=0$ est la seule solution possible.}\\
    \\

    \\
    \\
    \Large{b)}
    \\
    \\
    \Large{$\lambda<0$}
    \\
    \\
    \Large{$\Rightarrow y''-\lambda y = 0$}
    \\
    \Large{$\Rightarrow y = e^{rx} \quad \textrm{[ou y=0]}$}
    \\
    \Large{$\Rightarrow r^2 e^{rx} - \lambda e^{rx} = 0$}
    \\
    \Large{$\Rightarrow e^{rx}(r^2-\lambda)=0$}
    \\
    \Large{$\Rightarrow r^2-\lambda=0, \quad \textrm{car} \quad e^{rx}>0$}
    \\
    \Large{$\Rightarrow r=\pm\sqrt\lambda \quad \in \quad \mathbb{C/R}, \quad 
    \textrm{car} \quad \lambda<0$}
    \\
    \Large{$\Rightarrow r=0 \pm i\sqrt{|{\lambda}|}$}
    \\
    \Large{$\Rightarrow y=k_1cos(\sqrt{|\lambda|}x)+ik_2sin(\sqrt{|\lambda|}x), 
    \quad \textrm{car} \quad e^{0x}=1$}
    \\
    \\
    \Large{Or, $y(0)=k_1\neq0, \quad car \quad k_1,k_2 \in \mathbb{R}/0,$}
    \\
    \Large{\qquad ce qui ne respecte donc pas les conditions initiales.}
    \\
    \\
    \Large{d'où $y=0$ est la seule solution possible.}

    \end{document}
