first and second derivatives of these equations

Hi Guys,

I'm having trouble working out some equations mostly dealing with exponential and logs.

the equations are:

y= 2x + 3^(-12x)

y= x^(-2x) - (e^2x)/5

I need to find both the first and second derivative. Any help and explanation would be much appreciated.

Thanks guys.

Thank you! :wink: From my understanding the first one has to do with ln so dy/dx = 2 - 12ln3(3^-12x) I'm not sure whether I multiply the -12ln3 with the (3^-1...

Re:

Ouch! They were supposed to teach you that stuff before assigning homework on it! :shock: To learn how to work with exponential and logarithmic functions and their derivatives, try here . :wink: Thanks for helping. Im doing a master of finance course with no background knowledge on calculus. The le...
