# How do i inverse equation in simulink matlab

I have an equation with cos block and some other constants in Simulink how can I inverse this eqauiton to make it like 1/f? thanks

• Can you say a bit more about what you've already tried and what you're trying to acheive? – tobassist Jun 11 at 9:11
• Let $y=f(x)$. It is not clear if you are asking for the inverse function $f^{-1}(y)=x$, or the reciprocal of an input $a=1/u$, to say the least. – cjferes Jun 11 at 17:52
