Solve 1-cosa cosb-cos(a b)/1 cosa-cosb-cos(a b)

Evaluate

1 - cos a cos b - cos ab \div (1 \times cos a) - cos b - cos ab

Multiply

More Steps

1 - c^{2} o^{2} s^{2} ab - cos ab \div (1 \times cos a) - cos b - cos ab

Any expression multiplied by 1 remains the same

1 - c^{2} o^{2} s^{2} ab - cos ab \div cos a - cos b - cos ab
