These were easy. I'm in fifth

f= x^sin(x)
LN(f) = LN(x^sin(x)) = sin(x)LN(x)
e^LN(f) = f = e^(sin(x)LN(x))
f = e^u
u = sin(x)LN(x)
f' = u' * e^u
u' = ab' + a'b
a = sin(x)
b = LN(x)
a' = cos(x)
b' = 1/x
u' = sin(x)(1/x) + cos(x)LN(x)
f' = sin(x)/x + cos(x)LN(x) * e^(sin(x)LN(x))
f' is the slope of f at point x.
Take Calc 1.  Fun stuff.

Used Chain Rule and Product Rule (not sure about the name for that one.)

wow algebra is easy

i was just in 6th grade...

I didn't learn algebra until 10th grade.  At which point, I hit the 99 percentile in the country in test scores.  I'm going into 12th grade now.  Got a 4 on Calc AB AP test

It's just called the product rule.

I get to take a class on differential equations in a couple of weeks! Hot stuff

:D
I have to wait until my 2nd semester to take calc 2.  Basically, mid January. D:
