1. The problem statement, all variables and given/known data A particle moves along the y-axis so that its velocity v at time t is v(t)=1-(1/tan(e^t)) Find the time t greater than or equal to zero at which the particle reaches its highest point. 3. The attempt at a solution I set the equation equal to zero and got t=-.242 which doesn't work so I graphed it on a calculator to see what's going on. The graph ended up being a crazy graph with many, many zeros and I have no idea where to go from here.
