Help with Math problems please. I love you!

hi

i'm stuck at these two problems and hope someone in here could help me with my stupidity. thanks a lot

1. Write out at least the first three nonzero terms of the Maclaurin series for f(x)=sin2x
Then find the Maclaurin series for f(x)







2. Write out at least the first terms of Taylor series for f(x)=e to the x exponent at a=5
Then fine the Taylor series representation for f(x)

sorry i couldn't make the exponent symbol in here for e so hope this won't confuse anybody.

thanks so much. i need it as soon as possible cause tomorrow its due. thanks again

can't you get a tutor? I refuse to do your own homework. btw exponent is referred as ^

good luck

Asians are suppose to be good with math... what's wrong with you?

Wow, I don't even know how to help you, except suggest 2 things: 1. Learn how to do a taylor and maclaurin expansion
2. Read your textbook.

I'd be surprised if there wasn't an example for something like cos2x or cos3x.

Otherwise, I'd simply be doing your homework for you.

sin(2x) = 2 * sin x * cos x. Take the Taylor series of each and multiply them together. Done.

You're asking the most basic examples of Taylor and Maclauren series because these are the given formulas in any book and you only need modify what they have given you. Read the chapter in your book and you will clearly see how it is done.

sorry i was absent for 1 week from the class due to my grandmom has passed away. Thanks for the help. If you're in my shoe i don't think you guys would bash me like above.

thanks sir. i'll look info my text book deeper. but i dont have any notes and everything i'm very lost at the moment. i'll try my best.

This one is a decent starter example Text. Just google Taylor series or Maclaurin and you'll find tons of hits explaning it all.

can't you get an excuse for your hw? you have to learn this info some time
