Jul11 revised Differentiating $\frac{te^{\tan t}}{ln(3t+1)}$? edited title Jul11 comment Differentiating $\frac{te^{\tan t}}{ln(3t+1)}$? So I should use one of them or the other but not both? Jul10 reviewed Approve suggested edit on Differentiating $\frac{te^{\tan t}}{ln(3t+1)}$? Jul10 comment Differentiating $\frac{te^{\tan t}}{ln(3t+1)}$? Then I didn't need to use the chain rule on $e^{\tan(x)}$? Jul10 comment Differentiating $\frac{te^{\tan t}}{ln(3t+1)}$? @TylerHG Thanks for the heads up. Jul10 comment Differentiating $\frac{te^{\tan t}}{ln(3t+1)}$? Thanks for the help. But the way I was doing would also work, wouldn't it? (No, I'm not planning to use it, I'm just making the stupidity test on myself). Jul10 comment Differentiating $\frac{te^{\tan t}}{ln(3t+1)}$? @TylerHG Yes. It was a poor adaptation from portuguese. I thought one could employ "derive" in english. Jul10 asked Differentiating $\frac{te^{\tan t}}{ln(3t+1)}$? Jul8 asked Where can I find introductory video lectures about calculus and analysis?

Jun27 comment What's the importance of a formula for the real and imaginary parts of a complex number? I see. I still didn't read about complex numbers expressed in that way. I just discovered a few seconds ago that they are called complex numbers in the exponential form. Jun27 asked What's the importance of a formula for the real and imaginary parts of a complex number?
