The Summing template on the C Key how does it work?
    Product: HP Prime G2
I tried using The Sum that E for lists with i=0 and infinity sign above and the expression after the = sign.

I put the template on my Home page and added all the parts it did not work.

Does anyone know how to use it

I have tried it in CAS and without CAS still, this function does not operate for me.
Help needed.

The lower-case (script) i is the constant \( \sqrt{-1} \); use n for your index variable.

1. (Lower case) i is a reserved variable,
2. The angle mode should be set to radians,
3. Use == for the comparison.

Thank you I have done the following, however, the answer is 1.9 It should be
1.5 for pi/2 and the answer should be 1.

I can't do this in a function app. I had to do it in just the regular window under CAS.
Is that where I should be entering it.

It works fine in CAS.

The problem with what is shown in your thumbnail is that the \((2n+1)!\) in the denominator is outside the summation, which is why it still appears in the final answer.
