[1/1 Formula]
    Work: Calculate the value of equation 48×48+37×37-2×48×37×cos49 .
    Question type: Mathematical calculation
    Solution:
          48×48+37×37-2×48×37×cos49
        =48×48+37×37-2×48×37×0.300593
        =2304+37×37-2×48×37×0.300593
        =2304+1369-2×48×37×0.300593
        =2304+1369-96×37×0.300593
        =2304+1369-3552×0.300593
        =2304+1369-1067.706336
        =3673-1067.706336
        =2605.293664

    Answer:48×48+37×37-2×48×37×cos49=2605.293664
