Wrong values for inverse trigonometric function in Calculate Activity

[saurabhhere]

Below mentioned bugs are achieved from Sugarizer web (http://try.sugarizer.org/)

Getting wrong value of inverse trigonometric function when angle type is 'degree' :

For asin(0.5) expected value is 60 degree but we are getting 0.000152
Also the range for x in asin(x) is from -1 to 1 but calculator is showing value for x =2 also:

Same problems are with acos(x) & atan(x) when angle type is 'degree'.

[Suggestion] In case of tan, calculator is showing finite values for both tan(90°) & tan(π/2), we can either write infinite or not defined instead of showing a finite number.

Good shot. Thanks.
And it look like it's only in degree mode.

@mikklfr do you think it could be related to the automatic degree to radian conversion here?

hey @llaske! is anyone working on this issue? i would like to contribute should i go ahead?
