# Integrate of sec(x) HP Recommended
HP prime

Hi, I'm learning how to use the HP Prime, and I've noticed that when I integrate Sec(x) it gives me a long answer instead of LnIsecx+tgxI, also when I calculate a determinate including a SEC(x) it gives me a long result . is there a way to make it appear Sec in the results?

hello,

I do not know an easy way to accomplish  this conversion.

What I can do is this:   By multiplying both the numerator and the denominator of the trigoniometric expression by (1+sin(x)), the numerator will become (1+sin(x))^2 and the denominator (cos(x))^2

By taking its root and replacing the 1/2 in front by 1, the trigoniometric expression will become

(1+sin(x))/cos(x)=sec(x)+tan(x), which is the simple result.
