Hello, I need to write a conclusion for my math assignment report. But i never did it before, I wan to ask that how we consider t=30/cos Ө as?

is it an equation? or?

thanks.

What you wrote is just t as a function of $\displaystyle \theta$.

What that means, and how to best to describe it, depends on the specifics of the problem where that function arises. - Sep 19th 2012, 12:51 AMAuXianRe: How to explain it in words?

Maybe use the secant function to "describe" it? Is that the kind of description you're looking for?

$\displaystyle t = 30 \sec(\theta)$ - Sep 19th 2012, 11:02 PMAuXianRe: How to explain it in words?

Any of those is correct. Because is says one side = another, it is an "equation".

Because you can use it to find one value given another, it is a "formula".

Because you can think of a value of $\displaystyle \theta$ giving a value of t, it is a "function".

For your purposes, probably "formula" is best. - Sep 28th 2012, 08:03 PMAuXianRe: How to explain it in words?
