Statics - Centroid of a function example 3 

hello, i know this is an old video so i might not get a response. if i do, thank you for clarifying. for the first problem, wasn't it also possible to calculate the centroid by using the centroid formula of a semi circle since it is a common shape: (y hat = 4(r)/3π) and x hat = 0)

I think you did a mistake at the integers of y. mine is equal to: (1/2)*x - (1/12)*x³ + (1/160)*x^5

You did a mistake in 1st question
