-- i kno u guyz r smart! so if u help me, i'll luv u forever and ever~~~~~~~~ (https://www.jusunlee.com/forums/showthread.php?threadid=7235)

i kno u guyz r smart! so if u help me, i'll luv u forever and ever~~~~~~~~

ok..calculus isn't really my subject..so help me out here
if u can answer any of these questions and show work...i'll be so thankful..
try working from the last question and up cuz i think the last ones r the harder ones =.=
ok u have to find derivatives (spelling? dunno)
f(x) = (x+2) x^2 - 1
x^2 + x
f(x) = 3secxtanx

f(t) = (cos t sec t)^ 1/2

f(x) = cos^2 x - sin^2 x

f(x) = x 4^x

f(x) = (1/e)^x

f(x) = (e^x^2 + 1)^ 1/3

f(x) = sec (tan e^6x^2)

uh i did 4,5 and 7 cause they looked the easiest and i need to finish my own homework

4) [2cosx(-sinx)] - [2sinxcosx]

5) [x(4^x)(ln4)] + (4^x)

7) [1/3((e^x^2)+1)^4/3]*(e^x^2)(lne)(2x)


*got rid of the - exponent in the bracketed area

1:(x^2+2)/(x^2)....if dats wat u wrote....i cant quite tell wat it wuz
2:(3((sin x)^2+1))/(cos x)^3
3:0
6:(-e)^(-x)
8:too lazy to figure out.......
