Aug 16, 2012 · The syntax is different from Latex math formulas because label_parsed interprets labels as plotmath expressions. For example indices are written x_i in Latex and x[i] in plot math expressions, and Greek letters are written directly as alpha instead of \alpha in Latex. You can find many formulas in the help page of the plotmath function. The carrying capacity formula is a mathematical expression for the theoretical population size that will stabilize in an environment and can be considered the maximum sustainable population.The de Moivre formula (without a radius) is: (cos θ + i sin θ) n = cos n θ + i sin n θ. And including a radius r we get: [ r (cos θ + i sin θ) ] n = r n (cos n θ + i sin n θ) The key points are that: the magnitude becomes rn. the angle becomes nθ. And it looks super neat in "cis" notation: (r cis θ) n = r n cis n θ.Sample problem: test the significance of the correlation coefficient r = 0.565 using the critical values for PPMC table. Test at α = 0.01 for a sample size of 9. Step 1: Subtract two from the sample size to get df, degrees of freedom. 9 – 7 = 2. Step 2: Look the values up in the PPMC Table.
