WebFeb 2, 2024 · Because for t → 0 we have log ( 1 + t) ≈ t, we can conclude that x ≈ 3, but x < 3. The numerical value is about 2.8135880922155955. If you want, you can use the infinite series for log ( 1 + t), however, you need to remember that in your case the change of base is necessary: log 3 ( 1 − 5 27) = 1 log 3 log ( 1 − 5 27) = − 1 log ...

WebNov 4, 2015 · Simpson's rule approximates the area under a curve using a quadratic approximation. For a given h > 0, the area under the curve of f (x) between x0 and x0 +2h is given by: h 3 (f (x0) +4f (x0 + h) + f (x0 + 2h)) Try improving the approximation using Simpson's rule, using h = 1 2 then we get six approximate areas to sum: h 3 (25 6 + 73 30 … Weblog ( 1 + x 1 − x) = 2 ( x + x 3 3 + x 5 5 + ⋯) Let us apply it for computing the logarithm of 5 3 = 1.666667; this would correspond to x = 1 4. So log ( 5 3) = 2 ( 1 4 + 1 192 + 1 5120 + ⋯) = 3923 7680 ≈ 0.5108 Now, 166 100 = 5 3 × 249 250 So log ( 1.66) = log ( 5 3) + log ( 249 250) = log ( 5 3) + log ( 1 − 1 250) ≈ log ( 5 3) − 1 250 WebMay 9, 2024 · In this tutorial, we will discuss how to evaluate basic logarithms without a calculator. Most scientific calculators will only give you logarithms to base 10 or base e.
