The right-hand side is equal to zero, and now I just have to give an initial guess, and I'll just go right in between that interval between t equals zero and t equals six. So I'll just put a three right over there, and now I just need to solve it, and I can do that by hitting Alpha, and then Solve, and then you see it got us to 5.196. So t is approximately equal to 5.196, but remember, they're not asking us for at what time does the particle change direction. They wanna know what's the position of the particle at that time. Well, we know how to find our change in position. Our change in position is going to be our displacement from time equals zero to time 5.196, and the displacement, we're integrating the velocity function, so that's going to be two sine of e to the t over four plus one dt. Now, this is going to be our change in position, but where did we start?
