I get unexpected results when using the trigonometric functions on my Android 4.4.2 phone.
For example, if I enter sin(30)=
I get the result -0.9880316
when I expect the result 0.5
. It appears the phone expects trigonometric numbers to be expressed in radians rather than degrees which is uncommon - the phone's manual certainly did not mention it. Most calculators work in degrees. Decent calculators have a deg/rad/grad switch.
Is there a way to do this on the phone or am I forced to include a degrees-to-radians conversion in all my trig calculations?
