I'm using trig substitution to solve this problem. I know that x=2sec(theta) and so I know from this that dx=2sec(theta)tan(theta). Through trig I get that tan(theta)=sqrt(x^2 -4)/2. Using substitution I get the integral to equal ln|sec(theta) + tan(theta)| and resubstituting I get ln|x/2 + sqrt(x^2 -4)/2|. However the answer is ln|x + sqrt(x^2 -4)|. Where did I go wrong?

I don't understand, help explain?!

Explain the phrase "only certain organisms can change solar energy into chemical energy"

I'm supposed to be sure to identify--
the type of nutrition carried out by these organisms
the process being carried out in this type of nutrition
the organelles present in the cells of these organisms that are directly involved in changing solar energy into chemical energy

Does photosynthesis count?!

Why do we never hear of them? I have never heard of them before until I saw them on the map. Who lives there? Are they used for military bases? What is their political status? Do they have governments? Can they vote? Thank you for quenching my curiousity!

Its not like they are ever going to succeed. Everything that can be invented has been invented. All the other discoveries will be just minor improvements.

I need help with these pratice problems i have.

1. ^32x^3y^8

2. This one needs divided and simplify ^9 x^4 y^5/ 18xy^3

3. ^3 x^3 + ^4 x^6 -6^75 x^3

4. And if a triangle has sides of A=5 and C = 10 would the miss value of the other which is B would it be just 75 or 5to the power of 3 because I got 75 but when I reduce it i got 5 to the power of 3 i dont know if it means different when it aks the value?
