Some typos in my formulas in my thesis I found some typos (or errors) in my thesis, one formula, the label of one figure, and one citation. My thesis is done. What should I do? I know some students faked data and their degree were revoked. I did not fake data, but I am not sure how serious these typos are. 

UPDATE

I cited and used 5-6 statements from an online report A and changed a little of them. They looks similar. But citation is wrong. I cited B in reference. What should I do? Is it Plagiarism?
Now that you have discovered the issues, you need to get to the bottom of whether they matter. If they typos make the conclusions wrong, you have a more serious issue than if they don't change the overall results. 

It doesn't seem like a figure caption is likely to matter (unless it implies the exact opposite of the correct caption, like "Death Rate" instead of "Survival Rate"). 

An equation typo is unlikely to matter unless it invalidates a proof or gives the wrong values in the final form of an expression. You ought to be able to determine this now.

The citation mistake is annoying because a stickler could accuse you of plagiarism. I think that's unlikely, but it's probably worth fixing if you can.

My recommendation would be to show these three errors to your advisor (assuming your relationship is good) and ask for their advice. Helping out with these kinds of issues is their job. Also, they can probably help you navigate/find your university's policy for dealing with thesis errata. Given that pretty much everyone makes mistakes, I'd expect there to be some sort of mechanism for correcting inconsequential mistakes. 

If the errors are more important or change the results of your work, you're really going to need your advisor's help. I think talking to them and working through the consequences together are your best bet.
