tan x = 1/2
Can someone tell me what the radian value is for this number and how they got it? Thanks On a graph plot the point A(2,1) Let C(2,0) be the point on the x-axis x is the angle AOB and tan x = 1/2 Since angle x is not one of the special angles, you will have to use a calculator ...

Trig - tan 15° using composite argument?
tan 15° tan (45°-30°) (tan 45° - tan 30°)/1+ tan 45°tan30° (1-√3/3)/(1+1√3/3) then i donnt what to do/ chancel out. Can someone finish it if i didnt get it wrong. thanks in advance

I'm having a hard time understanding how to do Integrals involving tan^2. I have two problems: 1. Find the integral of (tan^2 y +1)dy 2. Find the integral of (7tan^2 u +15)du 1. My approach to it is to replace the tan^2 y portion of the problem with sec^2 y -1, but it doesn't ...

don't forget your trig identities tan^2+1 = sec^2 ∫sec^2 y dy is easy, right? 7tan^2 u + 15 = 7tan^2 u+7 + 8 = 7sec^2 u + 8 Now we're back to ∫7sec^2 u + 8 du
