hi,
i have a question about multivariable calculus. Is it required to know linear algebra in order to take a m. calculus course?
ohh, ok. thanks. i feel like a retard now. hehe
but what happens with the y = 1? i need it to find the limits. it can't be the upper limit because the graphs don't intersect there. they intersect when x = e in this equation: y = ln x, so the upper limit should be e. correct me if i am wrong and please tell me why i am wrong.
hi,
i have a problem with a volume question. it's the following:
Let R be the shaded region in quadrant 1 bounded by the graphs of y = ln x and y = 1.
find the volume of the solid generated by rotating R about the y-axis.
book-answer: pi/2 (e^2-1)
and i have another problem which i can't solve:
y = (cos x )^0.7x
thanks
omg i can't believe that i didn't think about that. sorry for doubting the answer
hmm,
the answer in the book is
f' (x) = x^5 * 3^x *(5/x + ln 3)
hi,
how do i solve the following problem:
f (x) = x^5 * 3^x
f' (x) = ?
thanks in advance
