Integral on hp prime app does not work

[Lela10]

I can solve most integrals but at some I must make a mistake as the app crashes. 

Here is what I entered, as soon as i hit enter, the app crashes

If you want to calculate a indefinite integral make sure if you are in "CAS MODE". As image bellow.

CAS MODE ON

If you aren't, push CAS button.

Please, mark Accept As Solution bellow, if it solves your problem.

See, the images, for indefinite an definite integral ...

 

In comparison with Wolfram Alpha ...

https://www.wolframalpha.com/input/?i=indefinite+integral+sin(x)

Note : The definite integral although they indicate the use of CAS and what you indicate as example, not have result, why "does not converge".

Hallo Lela. Guten Tag.

Noch ein Detail: ins CAS auswahl muss man die Ausdrucksvariablen in Kleinbuchstaben schreiben.

Thank you Rick.

I've seen the printscreen in German and then just answered without paying attention.

I just wanted to tell the author that in CAS option, variables must be expressed by small letters.

Hi!, @Ciro_Bruno :

With indefinite or definite integral's, in CAS, is same write letter's in lowercase or uppercase (see image) ...
