#int^{x}_{0}cos(#frac{#pi}{2}t^{2})dt");
l.DrawLatex(0.1,0.7,"2) C(x) = d #sqrt{#frac{2}{#lambdaD}}\
#int^{x}cos(#frac{#pi}{2}t^{2})dt");
l.DrawLatex(0.1,0.5,"3) R = |A|^{2} = #frac{1}{2}#left(#[]{#frac{1}{2}+\
C(V)}^{2}+#[]{#frac{1}{2}+S(V)}^{2}#right)");
l.DrawLatex(0.1,0.3,
"4) F(t) = #sum_{i=-#infty}^{#infty}A(i)cos#[]{#frac{i}{t+i}}");
l.DrawLatex(0.1,0.1,"5) {}_{3}^{7}Li");
