## simplification example...

I am curious whether anyone here can come up with a way to simplify the expression x1 to 15*Pi/32 in fewer exact, symbolic steps. The following was performed in Maple 2016.2 for Linux.

 > restart;
 > x1 := arcsin(1/2*(2+(2+(2+2^(1/2))^(1/2))^(1/2))^(1/2));

 > x2 := evalc(convert(x1,expln));

 > x3 := convert(x2, expln);

 > # non-Pro wolframalpha can simplify x3 to 15*Pi/32 (but not x2 or x1). #
 > x4 := combine(x3);

 > x5 := simplify(x4);

 > x6 := expand(x5);

 > x7 := combine(x6);

 > simplify(x7,constant);

 > # It's a pity that last step worked while this next is inadequate. simplify(x7);

 > # Another way, using x7 simplify(evalc(x7));

 > # Another way, using x7 simplify(combine(expand(x7)));

## expression with inverse trig funtion...

Hello

I am having issue in finding the explanation on how to solve inverse trig funtion and expression with inverse trig funtions. I do not understand my school book and I was hoping that the software would have given me an extra help in understanding my school problems.

Thank you very much

Regards,

Perla D'andrea
