a level trigonometric functionsWatch
i've attached my answers for 5a and 5b just in case they need to be used to work out 5c
Hey, for an inverse function , The domain is the range of the original function and the range is the domain of the original function
thanks for your reply. i know that the domain and range swap around, but i don't know how to express that in terms of f^-1(x)
First start by separating the y from x, u should get a linear. eqn = trigonometry function....then replace y for x.... It then become clear
Try rearrange the equation to make x the subject, then replace your x with a y and vice versa!
