let x = 2sin t  ∫ (√(2sin t−2cos t)) ×2cos t dt  ∫ (√(2(√(2 )) cos (t−((3π)/4)))) ×2cos t dt  2 ((8 ))^(1/(4  ))  ∫ cos t (√(cos (t−((3π)/4)))) dt  wait

$$\mathrm{let}\:\mathrm{x}\:=\:\mathrm{2sin}\:\mathrm{t} \\ $$$$\int\:\sqrt{\mathrm{2sin}\:\mathrm{t}−\mathrm{2cos}\:\mathrm{t}}\:×\mathrm{2cos}\:\mathrm{t}\:\mathrm{dt} \\ $$$$\int\:\sqrt{\mathrm{2}\sqrt{\mathrm{2}\:}\:\mathrm{cos}\:\left(\mathrm{t}−\frac{\mathrm{3}\pi}{\mathrm{4}}\right)}\:×\mathrm{2cos}\:\mathrm{t}\:\mathrm{dt} \\ $$$$\mathrm{2}\:\sqrt[{\mathrm{4}\:\:}]{\mathrm{8}\:}\:\int\:\mathrm{cos}\:\mathrm{t}\:\sqrt{\mathrm{cos}\:\left(\mathrm{t}−\frac{\mathrm{3}\pi}{\mathrm{4}}\right)}\:\mathrm{dt} \\ $$$$\mathrm{wait} \\ $$
