1. So I have to show 2sin^2(x) and -cos(2x) have the same antiderative.
Here's how I approached this.
2sin^2(x) = 1-cos2x ==> u = 2x
intergral of that is
(u - sinu)/2 + c = x - (sinx)/2 + c
-cos2x ==> u = 2x

$x = \frac{\log 12}{3}$
#### Explanation:
The first thing we do is subtract 7 from both sides:
${10}^{3 x} = 12$
Now we ad logarithms to both sides:
$\log {10}^{3 x} = \log 12$
One of the properties of logarithms is that we can pull the exponent to the front, like t... | 2021-10-22T22:25:28 | {"extraction_info": {"found_math": true, "script_math_tex": 0, "script_math_asciimath": 0, "math_annotations": 0, "math_alttext": 0, "mathml": 0, "mathjax_tag": 10, "mathjax_inline_tex": 1, "mathjax_display_tex": 0, "mathjax_asciimath": 1, "img_math": 0, "codecogs_latex": 0, "wp_latex": 0, "mimetex.cgi": 0, "/images/ma... |
