NO ONE GOT THIS! Integral of cos^-1(x)/cos(x) from -pi/4 to pi/4I GOT MY FIRST KLEIN BOTTLE (from Cliff Stoll)Doing integral of sec^3(x) ON THE SPOT!WHAT! Integral of (x^3+x)/(1-x^2)Head-to-head rounds are about to start!the answer key was wrongu never know when u need math!46 people got this integral rightHE DID IT SO FAST! Integral of ceiling of sin(x) from 0 to 16piWhy do we keep, change, flip or multiply by the reciprocal when we divide fractions?zero factorial is equal to 1 and 1 is not primeHE SOLVED IT NICELY! Integral of floor and ceiling functions
