Finally, if you negate everything and flip p and q (taking the inverse of the converse, if you're fond of wordplay) then you get the contrapositive. Again in symbols, the contrapositive of p → q is the statement not q → not p , or ~ q → ~ p . Dec 19, 2019 · “Leveraged and inverse leveraged ETFs are in a word, volatile. Investing in any form of leveraged ETF amplifies your exposure to the underlying index or commodity price.

Feb 11, 2017 · Meaning there is actually a second possibility here, if 5*F^2 +/- 4 is 5 times a perfect square, the expression in the log will still be a rational linear combination of 1 and sqrt(5). However, this is quickly seen to be impossible, since 5*F^2 is divisible by 5, the expression 5*F^2 +/- 4 always has remainder 4 or 1 when divided by 5 ...

Describe the inverse function. If a given function (f) gets an input (A) and generates an output (B) and there’s a function (f1) which needs an input (B) to generate (A), this means that (f1) is the inverse function of (f). This shows that antilog = inverse log. When looking at the formula, log (b) x = y has an antilog (b) y = x.
