The indefinite integral (wrt x):

1 / (bx+ax^2)

Or, if you like:

1 / [x(b+ax)]

I suspect that this is IBP's, but I think I need to perform an algebra trick first to make it work...I don't know...any ideas from those in the know?

I've seen photos of poisonous spiders taking out non-venomous snakes, but would the result be similar if the spider was non-venomous? Would a non-poisonous tarantula have a chance against, say, an average sized constrictor?

I'm trying to find out which is better for the planet... For plastic that can not be recycled (at least not anywhere near where I live)... Is it better to incinerate (burn) it or take it to the landfill where it will sit for the next few thousand years putting chemicals in the groundwater etc? Thanks for any thoughts and comments.

Since the airplane cruise at a high altitude already, doesn't it have enough power to go higher? I think I saw a movie on this once and was not sure about the science behind the constraints...

The Mayans predict that a Pole Shift will occur which means a lot of bad things on the planet.

(Like Tsunamis, Tornadoes, Hurricanes, Volcanoes, and Floods)

The reason to them is that the Earth will be alligned with the Sun on December 21, 2012 causing to what they believe the end of the world

i cant seem to understand this question; i tried it many times but still cant seem to get it.

a bat uses echolocation to find insects. waves can only be used to detect objects that are one wavelenghth long or greater. if the bats echolocation is to be able to detect an insect that is 0.450 cm long on a night when the temperature is 15 degreed celcius, what must be the frequency that it uses to locate the insect? (Hint: some bats use frequencies as high as 150 kHz)

how do i do this? please help!!
