Integration using Trig Substitution
Yes, I'm fairly certain that is a standard integral, and it comes out to: sin^{-1}y + C But I'm also fairly certain that I am supposed to solve this problem using the expression, substitution, and identity when I do the trig sub. Maybe I am overcomplicated the problem and should just stick to...- Brickster

Integration using Trig Substitution
So I should end up with: \int sec\Theta d\Theta} Correct? then I would get ln \left| sec\Theta+tan\Theta \right| + C- Brickster

Integration using Trig Substitution
as in changing the bottom from 1 + (sinx)^2 to 1 + y^2 ?I can get to: \int \frac{sec^{2}\Theta d\Theta}{\sqrt{1+tan^{2}\Theta}} But after that it makes no sense, I just get back to the original equation when I sub. again.- Brickster

Integration using Trig Substitution
Homework Statement \int \frac{cosx dx}{\sqrt{1 + sin^{2}x}} Homework Equations Expression: \sqrt{a^{2} + x^{2}} Substitution: x = a*tan\Theta Identity: 1 + tan^{2}\Theta = sec^{2}\Theta The Attempt at a Solution I have tried using Trig Substitution, but I end up getting an equation much...- Brickster

Trifunction Derivatives problem
The quotient Rule is: y= u/v y'= [(vu'-uv')/(v^2)] The product Rule is: y= uv y'= (vu'+uv') the chain Rule is: y=u^n y'=(n)(u^n-1)(u')- Brickster

How Does Projectile Angle Affect Range and Height?
Heh, this isn't complex at all. In high school, especially since your physics class just started, you won't have air resistance. You should be able to do this easily if you read the material or listen to the teacher in class. Do you have all of your kinematic equations memorized?- Brickster

Horizontal force with a crate at a 27 degree angle
The problem says at a constant speed, therefore a=0. Also, there is no friction slowing you down. F=ma, a=0, so the net force is zero. You need to find the vertical and horizontal components of the applied force. So F(applied)*cos(27)=F(applied,horizontal), and F(applied)*sin(27)=F(applied...- Brickster

Where Do Valence Electrons Go in Covalent Bonds?
In convalent bonds, when the atoms interact to form the bonds, where do the valence electrons, or clouds, exist. Do the simply loop around them in a chaotic figure eight of sorts, or do the electrons spin inbetween them? Is the realitive location of the the val. e-'s even know? And if the... -

Graduate Time and Atoms: Can they exist without each other
PhillipF, Antihydrogen is the antimatter counterpart of hydrogen. Whereas the common hydrogen atom is composed of an electron and proton, the antihydrogen atom is made up of a positron and antiproton. There are real no differences with the reaction of matter/time as apposed to antimatter/time.- Brickster

How Can I Easily Memorize the Periodic Table?
Thank you Goku, links are/were helpful I personally came up with, hi-he-lie-be bokay-n-o flu-knee, that's the first 10 small abbv of the main words strung together, it works for me -
