I understand our galaxy is called The Milky Way, and the planets are Mercury, Venus, Earth, and so on. But what is our solar system called? Do you think if we discover more solar systems out there were going to name ours?

I worked out the following problem by first integrating by parts, and then solving the second integral via trig substitution. After combining everything together, I got pi/288 as my answer, but the fnint function (which can calculate the numerical value of a definite integral) on my calculator is giving me a different answer. Please work out this problem step-by-step so I can see exactly how you are supposed to do it:


1. x arcsin(6x) dx from 0 to 1/6 (definite integral)

(which reads as x times the sine inverse of 6x).


I tried doing a U substitution for this problem, but I’m not exactly sure how you are supposed to do it, or if you have to do multiple substitutions before you can integrate. Please work out this problem step-by-step so I can see the correct approach:

2. x^2 (e^x)^(1/4) dx from 0 to 1 (definite integral)

(which reads as x squared times the fourth root of e^x; note that the entire expression of e^x is under the fourth root).

Scientifically speaking, did we come from nothing? There was nothing, then there was a "big bang" and there was suddenly something? If the universe always existed, how is that possible? How can something not have a beginning...and how could there be a beginning from nothing?
I wish my mind could grasp this.

Im having some difficulty deriving a trig function using the product rule.
5x(sinx+cosx)
Should I even be using the product rule on this equation? I mean it does have a multiplying structure.

Why do you think that?
Could time travel be much easier than you think?
