Description
Description:
When Type asin(45) and enter, It gives,
asin(45)
Error at 1: math domain error
This should give the answer as, 1.17522136 in radians & 67.3352241 in degrees.
Similarly,
When Type acos(45) & enter It gives,
acos(45)
Error at 1: math domain error
This should give the answer as, 1.90359441 in radians & 109.067925 in degrees.
Tested enabling both deg & rad the result was same.
Steps to recreate the defect:
- Power on OLPC
- Click on the calculate icon on home page.
- Click on the trigonometry Tab.
- Click on sin-1 option.
- Type “45”.
- Click on Enter.
- Verify the message displayed on the right side result text box
Actual Result:
Displayed error message as “Error at 1: math domain error” when tries to get the answer for sin-1 and cos -1.
Expected Result:
For asin(45):
1.17522136 In radians
67.3352241 In degrees
For acos(45:)
1.90359441 In radians
67.3352241 In degrees

I do not see the problem here: the arc sine function is only defined for x between -1 and 1, so the math domain error is correct.
