Whatever you did to represent the equation in your problem isn't working. I'm pretty sure I know what the function should be, but I would like to see what you are working with. Just re-post using straight text. Use ^ to indicate raising to a power, cos(x) or whatever to represent trig functions and enough parentheses to make sure the meaning is clear.
