\frac{\pi}{3}-\sin x\sin x\sin }$<br/>${=2\sin x(\frac{1}{2}\cos x-\frac{\sqrt {3}}{2}\sin x}$<br/>${\div \sin x\cos x-\sqrt {3}\sin ^{2}x+\frac{\sqrt {3}}{2}}$<br/>${=\frac{1}{2}\sin 2x+\frac{\sqrt {3}}{2}\cos 2x}$<br/>${=\sin (2x+\frac{\pi}{3})}$<br/>所以f(x)的最小正周期为${f=\frac{2\pi}{2}=\pi}$<br/>(2)"f(x)+m≤0对${x\∈\lbrack 0,\frac{\pi}{2}\rbrack }$恒成立"等价于"${f(x)_{\max }+m\leq 0^{n}}$<br/>因为${x\∈\lbrack 0,\frac{\pi}{2}\rbrack }$<br/>所以${2x+\frac{\pi}{3}\∈\lbrack \frac{\pi}{3},\frac{4\pi}{3}\rbrack }$<br/>${2x+\frac{\pi}{3}=\frac{\pi}{2},}${x=\frac{\pi}{12}}$<br/>f(x)的最大值为${f(\frac{\pi}{12})=1.}$<br/>所以实数m的取值范围为${(-9O,-1\rbrack }$12分<br/>19.(1)由题意知S${\because _{6}\neq 2s_{3},q\neq 1\cdots

}$..7分<br/>∴T。=(1+2+-..+${y^{-x-3}_{n}}$+[1+2+--+(n-1)].................9分<br/>${=2^{n}+\frac{n^{2}-n}{2}-1\cdots }$.........12分<br/>20.(1)因为${a_{n}=\frac{a_{n-1}}{2}+\frac{1}{2^{n-1}}(n\geq 2,n\∈N^{*})}$，所以${2^{n}a_{n}=2^{n-1}a_{a}+2}$，即<br/>${2^{n}a_{n}-2^{n-1}a_{n-1}=2,}$<br/>所以数列${\lbrace 2^{n}a_{n}\rbrace }$是等差数列,且公差d=2,其首项${2a_{1}=3}$<br/>所以${2^{7}a_{n}=3+(n-1)\times 2=2n+7}$，解得${a_{n}=\frac{2n+i}{2^{n}}}$<br/>${2)\quad S_{n}=\frac{3}{2}+\frac{5}{2^{2}}+\frac{7}{2^{3}}+\cdots +\frac{2n-1}{2^{p-1}}+\frac{2n+1}{z^{\theta

+\frac{1}{2^{s}}}${=\frac{3}{2}+}${z^{e}+x^{2}}$ ${1-\frac{7}{2}}$<br/>${=\frac{5}{x}-\frac{2n+5}{a+1},}$<br/>所以${S_{n}=5-\frac{2n+5}{2^{n}}}$12分<br/>21.(I)在△ABD中,∵${\cos \angle ADB=\frac{3}{5},\therefore \sin \angle ADB=\frac{4}{5}.}$<br/>sin∠CAD=sin(∠ADB-${\angle AcD,=\sin \angle ADB\cos \frac{\pi}{4}-\cos \angle ADB\sin \frac{\pi}{4}}$<br/>${=\frac{4}{5}\times \frac{\sqrt {2}}{2}-\frac{3}{5}\times \frac{\sqrt {2}}{2}=\frac{\sqrt {2}}{10}}$<br/>在△ADC中,由正弦定理得${\frac{Ac}{\sin \angle ADc}=\frac{cD}{\sin \angle CAD}=\frac{AD}{\sin \angle ACD}}${\frac{AC}{\frac{4}{5}}=\frac{cD}{\sqrt {2}}=\frac{5\sqrt {2}}{\sqrt {2}}}$<br/>解得${AC=8,CD=\sqrt {2},}$<br/>${\Pi)\because \overrightarrow {CA}\cdot \overrightarrow {CB}=48,}${8\cdot cB\cdot \frac{\sqrt {2}}{2}=48.}$解得${c_{B}=6\sqrt {2},}$∴BD=CB-CD=5√2<br/>在△ABC中,A${B=\sqrt {8^{2}+(6\sqrt {2})-2\times 8\times 6\sqrt {2}}=2\sqrt {10}}$，在△ABD中<br/>${\infty \angle BAD=\frac{(2\sqrt {10})^{2}+(5\sqrt {2})}{2\times 2\sqrt {10}\times 5\sqrt {2}}=\frac{\sqrt {5}}{5}}$<br/>22.(1)由${\sin ^{2}=5}=S_{n}-5_{5}}&{T_{6}^{z}=-7}}${s_{w}^{2}=(S_{w}-S_{6-1})(s_{w}-\frac{1}{2})=s_{e}^{\vec {x}}-\frac{1}{2}S_{\varphi }-S_{6}=+\frac{7}{2}s}$<br/>${\therefore \frac{1}{s_{n}}-\frac{1}{S_{n-1}}=2(n\supseteq 2)}$<br/>${\therefore \left\lbrace \begin{array}{l}{\frac{1}{s}\rbrace
