me: hey namtutor, quick question
me: can you explain how to do product rule?
Sunday 7:02 PM
namrich: to get the derivative?
me: yes
namrich: um
namrich: how about you give me the question and i'll explain how to do it
me: okay
me: d/dx = (x^2-1)(x+5)
namrich: okay what does u and v equal?
me: where did you get u and v from
namrich: they are just tools to help you sort things out
namrich: u is the first part of the multiplication and the v is for the second
me: oooh, i remember my professor saying something like that
me: u=x^2-1 and v=x+5?
namrich: yes so what is the derivative of u?
me: u'=2x-1?
namrich: 1 is a constant so it is equal to 0
me: u'=2x?
namrich: and v'?
me: v'= 6?
me: no wait, v'= 1
namrich: yes, yes
namrich: good job
namrich: then you use this formula, u'v + uv'
me: i thought it was u(dv/dx) + v(du/dx)
namrich: it's the same thing
me: oooh okay
me: (2x)(x+5) + (x^2-1)(1)
namrich: okay great!
namrich: now simplify it
me: how do i do that
namrich: distribute the 2x and then combine like terms
me: 3x^2+4
namrich: you forgot to distribute the 2x to the 5
me: ooooh wait
me: 3x^2+10x-1?
namrich: wow, you are smart!
me: no, i'm not
me: that was rough
me: i'm going to fail college
namrich: no you won't
me: um yes i will
namrich: i don't believe it
me: well i do
me: hey, do you think the middle part of the oreo is better or the cookie part?
namrich: why do you ask?
me: my friend is insisting that the cookie part is the best but i think it's the middle part
me: idc, the middle is the best and no one can change my mind
namrich: light without darkness, darkness without light
namrich: one can't exist without the other
me: ...it's just a cookie
me: but that was deep
me: whoa
namrich: ahaha
me: you know, you remind me a lil of namjoon
me: he's smart and he is deep too
namrich: oh i do?
me: yes, you're very similar to him but i'm sure you're not as good looking as him
me: no offense
namrich: none taken
me: have you checked them out yet?
namrich: oh yeah, i have
me: did you turn gay
namrich: ahaha
namrich: was i suppose to?
me: yes, they have the power to make all straight men question their sexuality
namrich: lol they do?
me: yes, it's a fact my dude
namrich: i didn't know it was a fact
me: yes it is
me: oh wait, are you okay with me casually texting you like this or do you want me to stop?
me: i know some people don't like that
namrich: no, i'm fine with it
namrich: but please don't share my number around
me: i won't!
me: it's because you don't want more people to tutor?
namrich: right
me: gr8
me: :)))
me: you're nice
namrich: thank you
namrich: i try my best to be
me: :)
