Hi All, Having a shocker with this one aswell. If x = tan theta + sec theta, use the t formulae to show that (x^2 - 1) / (x^2 + 1) = sin theta I am lost with one. Thanks

Thanks And you think the whole world knows what the "t formulae" is? Same things can be taught very differently in different parts of the world... , so: Tonio
