anonymous 5 years ago what is the generic equation for a exopential function? and how would you figure out what i sin or cos function is?

1. anonymous

do you mean e^x written as a power series

2. anonymous

e^x can be written as 1 x + x^2/2! + x^3/3!+.... by McLaaurins theorem Also series for sin x and cos x can be written as series using the same theorem

3. anonymous

sorry - that should start 1 + x + x^2/2!

4. anonymous

thanks, all i understood was the e^x part but thats all i think i need to know. so all it would be is like 2^x or wtvr?

5. anonymous

That i sin, it's that French guy DeMoirve.

6. anonymous

what chagunanas?

7. anonymous

yes 2^x, 3^x and so on are exponential function

8. anonymous

thx a million!!!!!!

3-4i=$5(\cos \theta +i \sin \theta)$=$5(\cos 307 degrees +i \sin 307 degrees)$
