You should change whatever is it you said there. Members only? So much for knowledge for all!

You are right about "Members Only" part. However, if you checked a little bit more you would find out that membership to TuLyn.com is free. I guess I can still call it "Math For All" even though we have some paid services.

A Ferris wheel is built such that the height

h (in feet) above the ground of a seat on the wheel at time t (in seconds) can be modeled by 70+ 51 sin ( π/18 t - π/2). The wheel makes one revolution every 36 seconds and the ride begins when t = 0 . During the first 36 seconds of the ride, when will a person, who starts at the bottom of the Ferris wheel, be 70 feet above the ground?
