is there a special way to solve x(t)=10t+4sint (x(t)=140) using your calculator? x(t)=10t+4sint=140 answer is t=13.6
you can use newton method + calculator
could u explain? All I did was plug it in to my calc and then find where x equaled 140 so i got a rough estimate of 13.6ish
if you're allowed to use calculator, thats fine right ?
yes but there isn't a faster way? cuz i like manually trace in my calc. I'm in parametric mode cuz that's the equ i have
try finding x intercepts of : `x(t) = 10t+4sint-140`
or may be find the intersection of below two curves : x(t) = 10t+4sint x(t) = 140
whichever is easy..
got it! Thank you!!
np :) you dont wanto manually solve it is it ?
if u dont wanto use scientific calculator, u can solve this using `newton's method + store calculator`
well I'm allowed to use a calc on this portion. It's a part of a free response from a calc BC ap test. They don't require us to solve it manually. If we did though wouldn't it take a lot of steps?
yes eventhough newton's method is cool, it does take many steps and can be a pain lol
go wid the calc :)
haha TG for Calculators. Thanks again(:
