My first choice would be to convert this product to a sum of trigonometric functions. You can either work out the formulae yourself or...

Yep, i think you are right, found this below at https://mathshistory.st-andrews.ac.uk/HistTopics/e/

First, they are all equivalent. My recollection is that the series whose limit equals the definite integral for the hyperbola was the...

My source about Z-test was from one of my high school teachers. I no longer have the original photocopy of the lecture, but I still have...

Expand sin(5x)sin(2x) for 3 terms When I tried to get the coefficients for each term I have to deriviate too long functions For instance...

Thanks, sir

Looks good except, you need brackets in your third line and you've lost a power of x in the last line. Other than that it is correct.

So, what is your source, and what does it say? I expect that the n>30 rule of thumb is based on any one sample having 30 elements, so...

BTW HERE is a complete solution!

What if y=2? Then 3^(3+y^2) = 3^(3+2^2) = 3^(3+4) = 3^7= figure that out on your own You can raise 3 to any power, including 3.

That makes sense. Though am just seeing this for the first time .

I think it is wrong because of the right side 3^{(3 + y^2)} Since I began solving mathematical problem, I have never seen index upon...

x= ln(e^x) (x)' = (ln(e^x))' 1 = (1/e^x)(e^x)' Therefore, (e^x)' = e^x
