Sorry I'm still very confused,
how can we find omega or t or A or B from any of the given information?
my book just doesn't explain at all how to handle this type of problem
and also thats the first time I've seen an equation written that way
I have seen the x(t) = Acos(w*t) and the...

thanks for your help It's just been a while since calc I and i kinda forgot how to do limits
and yes one of the answer choices is that the integral diverges
well doesn't the 8- with the negative sign to the right of the number mean +8 but that it is approaching from the left side?
or are you saying that it means I should have plugged in a negative 8 for a?
or does that mean that that factor goes to infinity?
I'm not really sure how to write it in there with this program but I did take the limits individually when I did the work on my paper. The first bracket is the limit from 7 to a as a approaches 8 from the left and the second bracket is the limit from a to 9 as a approaches 8 from the right. Did...

it is integrated from 7 to 9 and i am aware that there is an infinite discontinuity at x=8 so we have to take the limit from both sides individually.

How much torque must the pin exert to keep the rod from rotating?
(L=1.011m , M=3kg , m = .301kg)
So I am guessing the point of rotation is the pin??
But then how does the pin exert any torque if it is at the point of rotation?
I'm not quite sure
there is a...
I have this problem i have been trying to solve and can't seem to get it right. The question states:

I’ve got this tricky trig substitution that I’ve been trying to do as for my Calc II class. I think that I’ve done the substitution part right I just have no idea where to go from here. I’ve tried many routes including integrating by parts as well.
Please help me thank you...
