Thanks everywhere. My steps were actually correct. I learned that I should draw diagrams next time I do these problems.

Well, arctan(1/(x^2-1)) is the same as arccot(sqrt(x^2-1)). I just don't know the mistake I did when showing my steps.

Homework Statement What is the integral of sqrt(x^2-1)/x dx? Homework Equations The Attempt at a Solution ∫ √(x^2 - 1) dx / x let x = sec u: u = sec^-1(x) and tan u = √(x^2 - 1) dx = sec u tan u du now the integral becomes ∫ √sec^2(u) - 1) sec u tan u du / sec u =...

Question: A projectile is fired down an incline which makes an angle of 40 degrees to the horizontal. The initial velocity of the projectile has a speed of 10m/s and makes an angle 60 degrees to the incline. Calculate the maximum perpendicular distance of the projectile from the incline...

The school emailed me back and they said that I'll need at least low 80s during my first year. Also, once I get accepted, I'll start from term 1 of the nanotech program. Some courses I took first year can replace some first year nanotech courses but the core courses will have to remain. I have...

I'm still in gr.12 and going to UW next year. Just curious if anyone has an answer to my question. Thanks. Oh by the way, I'll be taking physics, math, chemistry and biology during my 1st year.
