Hello All,
I have come across a typical calculator error recently - which i made myself.
When i was solving a 6 mark question at the end of a GCSE paper: i tripped up on my first line.
I had to solve: x =10Sin57 which was the first step in a complex question,
I got the wrong answer - which i knew because it was out of place compared with the other side of the triangle.
This may sound seriously silly to some people but the mistake can be made
:eek: I simply had my calculator in Radians Mode:eek:
To change it back to normal - i pressed [mode] followed by [mode] until an option of Degrees, Radians and Gradians came up, i simply pressed 1- which was Degrees and it was sorted out.
:cool: Be Careful:cool: , on the GCSE exam day make SURE your calculator is set on Degrees otherwise a maximum of 3 or 4 out of 6 can be awarded even if you did everything else correct
Thank You.
