Your ability to explain complex topics in a short and engaging manner, is really what separates you from other teachers. Thank you.

Can you explain why this is done in radians? Only because I don't know!

Thanks a lot for your help Jack.
I am just wondering that, would it be okay to write the answers of 2sin(0.2) and the rest to 4 decimal places and then use them in the trapezium rule formula? as the answer would be the same.

Will we ever have to work out the table in our heads, or can we always just use the Table function on the calculator?
