Please refresh my memory on exponential stuff

Postby triplesports17 » Fri Feb 13, 2009 6:09 am

If i am taking the dot product of for example < e^(x) , sqrt(2) , -e^(-x) > DOT < e^(x) , 0 , e^(-x) >

when i am multiplying the e^x terms do they become 2e^x or do they become e^(2x)... I cannot remember.

Thanks

If you're unsure in future, try an example with actual numbers:
