I'll just hit Enter. Equation Solver. So I could just say, look, the left side of my equation is two sine of, we are going to go e to the, I'll just use x as what I'm solving for because it's easier to type in in the calculator, and close that parentheses, plus one. 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.
