About the scientific calculator --- Wrong Answers
Why can't the calcuilator answer a simple question like sin(30) or cos(30) etc. when it is in the 'degrees'-mode?
With a number on the display nothing happens when you push the sin, cos or tan -button.
In 'degrees'-modus and the value 0.5 on the display en hitting the sin-1 button I expect 30 (degrees) in return.
But the calculator answers in radians !!
And why does it come up with Pi as a value equal to 3, when I use Pi in a (flowing) calculation?
30/180xPi should be 0.523598 ...
While your calculator says 0.5 !!!!
And why does the modus-shift button not change from RAD to DEG when radians are active?
Total useless this 'tool'
Your correct, it's wrong.
