Trigonometry, integral, multidimensional, differential calculus, plus severe time pressure to think through the answers. This is how the duel among mathematicians goes.
Math duel rules:
• two participants are given a math problem
• the first person to give the correct answer wins the round
"Participation in a math duel demonstrates the participants’ competence and their passion for higher math," say the organizers.
Congratulations to our students on the victory!
