It continues to amaze me that people are willing to follow a tumblr like this. I will try my best to be a little more consistent with my posts.

[[MORE]] 1. f(x) = log base 2 (1-3x) First apply logarithmic base-change rule where: log base a (x) = ln(x)/ln(b)...

1. f’(x) = [-3/[(1-3x)ln2]] 2. f’(x) = 1/(x^2+10) * 2x 3. f’(x) = (sinx)(1/5x) + cosx ln(5x) 4. f’(x) = [1/((xe^x)ln5)]...
