 sqrt{2}  sin(45)  -  cos(30) times  sin(60)  +  cot(45)  times  tan(135)  -  tan(0)  =  sqrt{2}  times  frac{ sqrt{2} }{2}   -  frac{ sqrt{3} }{2}  times  frac{ sqrt{3} }{2}  +  cot(45)  times  tan(180 - 45)  - 0 = 1 -  frac{3}{4} -  frac{1}{ tan(45) }  times  tan(45) = 1 -  frac{3}{4} - 1 =  -  frac{3}{4}   \  \  \ 2) frac{ sqrt{3} }{2}  +  sqrt{2}  times  frac{ sqrt{2} }{2}  -  sqrt{3}  times  sqrt{3}  =  frac{ sqrt{3} }{2}  + 1 - 3 =  frac{ sqrt{3} }{2}  - 2
