Thread: Complex Number Exponential Differentiation

Very confused on this topic, if possible could someone go through step by step how to do 19b and/or 20a (or b).



Sorry it won't seem to upload the right way around. Thanks for any help

Please either post a readable attachment or better yet learn to use Latex.
We cannot help if we cannot read the posting.

Is this viewable?

For all three, rewrite all the sines and cosines in terms of exponentials.

Yeah, I can do that. The only part that confuses me is the effect of the 51 in 20a

Show what you have done and exactly what about the 51st derivative confuses you.

I have Re [(1-[root3]i)^51*e^t(1+3i)]

Where do I go from there?

For 20b I have:

-[root2]^75*e^t(cost + isint)

Not sure where to go from there either.
