 Jul2 awarded Curious Jun26 comment Trigonometry / Finding the exact value Do you understand that that the cosine function obtains the same value every $2\pi$? Jun24 answered Problem of quadratic equation Jun24 awarded Yearling Jun20 awarded Nice Answer Jun5 comment How do you solve this using only given values, logarithm rules and no calculator? You can introduce $\log(2)$ easily. $\log(4) = 2\log(2)= 0.6021$. Jun3 revised How do I prove $\frac{ \sqrt{x+h}-\sqrt{x} }{ h}=\frac{1}{\sqrt{x+h}+\sqrt{x}}$? edited tags May22 comment Inequality involving conjugate numerator/denominator pairs Are you there? Chat is up now. May22 comment Inequality involving conjugate numerator/denominator pairs I would explain the full process to you, but the chat is offline. You can cancel the $x^3$ as a start. May20 comment Inequality involving conjugate numerator/denominator pairs Yes, that's just the wavy-curve method. It's just that you put alternate + and - between the intervals. May20 comment Inequality involving conjugate numerator/denominator pairs Don't worry. Do you know how to solve $(x + 2)(x + 4)(x + 7) < 0$ otherwise, without expanding it into a polynomial? May20 comment Inequality involving conjugate numerator/denominator pairs $(x+2)(x+4)(x+7) < 0$ is another way to say that something is negative. Have you ever used the wavy-curve method? May20 comment Inequality involving conjugate numerator/denominator pairs Corrected it. By the way, you should use the second method.
