Hey, could someone v. quickly go thru the calculator process of solving h = 5 + 4.5 sin ((Pi x t)/2) when t = 5 I've got 5.61, as im creating a table, just wanna check im doing it right....thnks

Your calculator is currently in degree mode. It should be in RADIAN mode.
now i get 31.5, is that right??

ok .....could you please show me how to do it on a calculator...i don't know what im doing wrong either
