Calculus

Hello

Can someone please help with my final maths question, It is Intergration and am struggling.

A current i=25sin 100Pi mA flows in an electrical circuit. Determine using intergral calculate, its mean and RMS values correct to 2 decimal places over the range of t=0 and t=10ms.


Thanks in advance

David your formula doesn't look right to me. Surely there should be a 't' in there somewhere?
Maybe i=25sin 100Pi t?
By the way it's integration not intergration and integral calculus not intergral calculation.
Can you check your formula and get back to us please?
Thanks
