Thank you. Whenever the object is rotating around an axis that's not the x-axis or y-axis I always get confused.
I'm confused on how you got the "4/pi" in front of sin(pi x)
My answer was right except the last sign. It was supposed to be a (-) but I had a (+).
I think x=0 might be one of the critical values but I'm not sure
I just realized my calculator was in degree mode so I'm pretty sure that is the reason I was getting the wrong answer
My calculator kept giving me -0.004784853 but it's probably just because I was putting it in wrong. Thank you.
I posted the wrong question and didn't want to edit it because last time I edited a question after I posted it someone got slightly upset. I figured just posting the actual question hours later would be better.
I'm absolutely clueless on what to do or where to start
Sorry for the late response but I understand now. I didn't even see the product rule between t^2 and sin(t).
