[1/1 Formula]
    Work: Calculate the value of equation 48×48+37×37-2×48×37×cos34 .
    Question type: Mathematical calculation
    Solution:
          48×48+37×37-2×48×37×cos34
        =48×48+37×37-2×48×37×-0.84857
        =2304+37×37-2×48×37×(-0.84857)
        =2304+1369-2×48×37×(-0.84857)
        =2304+1369-96×37×(-0.84857)
        =2304+1369-3552×(-0.84857)
        =2304+1369-(-3014.12064)
        =3673-(-3014.12064)
        =6687.12064

    Answer:48×48+37×37-2×48×37×cos34=6687.12064
