Arrange these in order from least to greatest: arctan(sqrt3), arctan 0, arctan(1/2) So far I got the first two values, arctan(sqrt3), and that's 150 degrees. Arctan 0 would be zero degrees. I'll use just one answer for now, but

Let f be a function defined by f(x)= arctan x/2 + arctan x. the value of f'(0) is? It's 3/2 but I am not very clear on how to obtain the answer. I changed arctan x/2 into dy/dx=(42x)/(4sqrt(4+x^2)) but that's as far as I got.

Note that pi lim arctan(x ) =  x > +oo 2 Now evaluate / pi \ lim arctan(x )   x x > +oo \ 2 / I'm not exactly sure how to attempt it. I have tried h'opital's rule but I don't believe you can use it here. Any help

also: integral of tan^(1)y dy how is integration of parts used in that? You write: arctan(y)dy = d[y arctan(y)]  y d[arctan(y)] Here we again have used the product rule: d(fg) = f dg + g df You then use that: d[arctan(y)] =

limiting position of the particle
A particle moves along the x axis so that its position at any time t>= 0 is given by x = arctan t What is the limiting position of the particle as t approaches infinity? Answer is pi/2 How do I solve this? Thanks a lot. You want

Now we prove Machin's formula using the tangent addition formula: tan(A+B)= tanA+tanB/1tanAtanB. If A= arctan(120/119) and B= arctan(1/239), how do you show that arctan(120/119)arctan(1/239)=arctan1?

h(x)= integral from (1, 1/x) arctan(2t)dt part 1: let U= 1/x and du= ? > using u=1/x, we can write h(x)= integral from (1, 1/x) arctan (2t)dt as h(u)= integral from (1,u) arctan(2t)dt and h'(u)= arctan (2) Part 2: By the chain
