We then multiply that by 2a giving: r = 2a(1 + cos()) [0,4a] This is the ditance to the origin, which could be at any angle, so let's make our axes, x and y run from 4a to +4a just in case: Next, it's useful to make a table of . \( a^2 + 4 - b^2 = 0 \) The function cos() has a range [ 1, + 1] so the quantity in parentheses 1 + cos() has a range [0,2]. For further elaboration, the authors got $\dfrac{dy}{dx} = \dfrac{2xy}{x^2 - y^2}$ from $x^2 + y^2 = 2Cx$. Here the weights can be arbitrary so long as N 1n = 0pn = 1; one obvious choice is pn = 1 / N which gives the maximally-mixed state = 1 2I, but there's plenty of other possible choices. MathJax reference. They have numerous properties, which make them useful in areas like solving polynomials and approximating functions. Now my problem with the book, right on the first page of chapter 1: He has the limits of the integral on the polynomial form as $[-1,1]$. For the case the denominator also is 0, but then in the sum we add 1 N-times, so we get N as a result for the sum. 2 Then, Using a calculator, we find that 2.74 radians, or 157.4. Can you please be more precise with regards to what's wrong with my/the textbooks calculations? Thus, if I plug in $x = \cos\theta$ into the polynomials $\cos m\theta$ and $\cos n\theta$ I would get $T[m](x)$ and $T[n](x)$ in the integral, and applying the chain rule with (3), the integral becomes: (6) $$\int_{-1}^1 \frac{T[m](x) \cdot T[n](x)}{\sqrt{1-x^2}}dx $$. \end{bmatrix} \end{bmatrix} Let's start with the given family of curves r = c(1 + \cos{\theta}).
