i don’t remember learning this in my calc class at all.. but now i will remember it forever since it’s such a help in my numerical analysis homework. i find it extremely amusing.
the answer is f(x).. too simple huh? i really love it 😉
i did good on my calc III midterm today. the teacher actually let us looked at the keys after the exam. i missed one problem which i thought was a hard problem. draw a contour graph of z=(x^2+1)*y.. i could only come up with a upside down parabola. of course it’s not a parabola to begin with.. doh =P
