(arctan . x) is 1 / (1 + x. 2)? 5. What gives us the right to plug in . x = 1 into (3) when the formula (2) that (3) was obtained from holds only for | x | < 1? 6. It’s just weird to prove a fact about numbers like . by considering a fact about functions like tan . x. Let’s take these one by one. 1. For any particular value of

Conversion of the measured parallax angle to radians is easy: [rad] = ( [deg]/360) x 2π ≈ tan , to be used in equation (2). Note that equation (1), rewritten to = arctan (R/D) = tan-1(R/D) is used to compute the scale factor, where R is the separation of the lines on the background chart and D is the distance to each row of seats in your ...

Just like when you substituted x2, you substitute in x+2. Here’s how you do it. Let’s do one last example. Recall that the Taylor series for ln(x) is the following: Now find the Taylor polynomial for ln(1+2x). Just do some plugging in! Let (1+2x) equal the x-value in the ln(x) Taylor expansion.
