Hi guys, I have a calculus test tomorrow and it'll be great if I can recieve some answers + explanations! my review sheet is attached. if this is breaking the rules im sorry. hope this actually helps some other people too
for #2) its log(x)/log4 b)then graph it with my TI89 then find the deriv @ .4 at work right now so no calculator on me =) btw: does the TI89 have a test function == like the ti86?
#3) f'(x)=2+cosx so we have to prove f'(x) is constantly positive or negative.. but how would we approach that?
sorry im not quite following you. on the y axis it is -1, and on the x it can be -infinite. please correct me if im wrong
i got x-4=y^3+y so turn my ti89 to parametric mode and y1 = t^3+t y2= -1 right? (since its g(3) 3-4 = -1) then i trace for a zero?
just came back from my test and i got confused on a question... find the deriv of x+sin(xy) i got (-sec(x)-y)/x but the calc gave me 1 thanks to all the people that replied and (attempted to) help
