  • Rolle's theorem without a given interval?

    Your answer: 
    I have a question in which I am supposed to prove that a function only has one real root. Due to the context, it appears I should use Rolle's theorem. However, I don't have a given interval. How do I prove it only has one root? It's a cos function.

  • Inverse function Bidmas?

    Your answer: 
    I was given the question f(x)=e^5-y/2 +6 and was asked to find the inverse function. When i did the question i did this... ln(x)=5-y/2+6 ln(x)-11=y but the answer is 2(5-ln(x-6)) Why is that the answer since in bidmas you deal with indices before you subtract so you'd have ln(x) rather than x-6 first.
