# C2 Trapezium Rule Question/Query Watch

1. From WJEC June 2007;

1. Use the trapezium rule with five ordinates to find an approximate value for the integral

I am not having a problem with the trapezium rule but my y figures are not the same as the mark schemes.

Maybe i am inputting them into the calculator wrong, but i have tried to work out whats going on but i cant seem to figure it out.

Any help would be appreciated.

You need to be in radians. Not degrees.
