$$\mathrm{5cot}\:\mathrm{10}{x}−\mathrm{1000}=\mathrm{1000} \\ $$$$\mathrm{5cot}\:\mathrm{10}{x}\:=\:\mathrm{1000}+\mathrm{1000} \\ $$$$\mathrm{5cot}\:\mathrm{10}{x}=\mathrm{2000}\Rightarrow\mathrm{cot}\:\mathrm{10}{x}=\frac{\mathrm{2000}}{\mathrm{5}}=\mathrm{400} \\ $$

$$\mathrm{tanx}=\mathrm{1}\Leftrightarrow\mathrm{x}=\frac{\pi}{\mathrm{4}}+\mathrm{k}\pi \\ $$
