what the heck do you do after this

are those 9's inside radical ?

sat_chenBest ResponseYou've already chosen the best response.0
you dont have to write the whole steps like last time can you just give me advice and yes they are

and you can just make them easy by making them into (3/7x)^2

sat_chenBest ResponseYou've already chosen the best response.0
dw:1359530730683:dw (3/7x)^2 something like that for the bottom part

when you do it can you confirm that you get the same solution as in my solving part and help me from there on. thanks

dumbcowBest ResponseYou've already chosen the best response.0
ok i get same solution (i simplified the constants) \[\frac{343}{81}(\frac{\sec^{3} \theta}{3}  \sec \theta) +C\] now you have to substitute back in "x" \[\tan \theta = \frac{3x}{7}\] and \[\sec^{2} \theta = \tan^{2} +1 = \frac{9x^{2}}{49} +1 = \frac{9x^{2} +49}{49}\] take sqrt to get "sec" , then cube that to get sec^3

sat_chenBest ResponseYou've already chosen the best response.0
so you wouldd ger 3x +7 /7 ?
 one year ago

dumbcowBest ResponseYou've already chosen the best response.0
no it would be ... sqrt(9x^2 +49) /7 because of addition inside you can't just take sqrt of each term

yep ... oh dont forget the 3 in denominator probably need to s.continue to simplify

sat_chenBest ResponseYou've already chosen the best response.0
but hold on my angles look like this dw:1359532285169:dw
 one year ago

dumbcowBest ResponseYou've already chosen the best response.0
hmm hypotenuse should be .... sqrt(9x^2 +49)

sat_chenBest ResponseYou've already chosen the best response.0
oh f i see why i forgot to square. its 2am and i had a long day .

dumbcowBest ResponseYou've already chosen the best response.0
haha time to get some sleep ....have wolfram do work for you

sat_chenBest ResponseYou've already chosen the best response.0
yep just finished it got the right answer thanks a lot time for bed i cant even think straight right now

dumbcowBest ResponseYou've already chosen the best response.0
yeah about 1 am here in AZ (best state)

sat_chenBest ResponseYou've already chosen the best response.0
and dont use wolfram like to get these things down myself
 one year ago

sat_chenBest ResponseYou've already chosen the best response.0
taking engineering math not my strongest subject but where the jobs go i go XD
 one year ago

dumbcowBest ResponseYou've already chosen the best response.0
nope... finished with college , i work as a math tutor so i come on here to practice and help people
 one year ago

sat_chenBest ResponseYou've already chosen the best response.0
hmm so you planning to be a teacher you would be a good one
 one year ago

dumbcowBest ResponseYou've already chosen the best response.0
engineering is great field but tough classes have to take quite a bit of math

sat_chenBest ResponseYou've already chosen the best response.0
yep still got to diff linear algebra etc good night bed is calling for me :P

i qualified to be a teacher but am undecided .... i prefer tutoring 1 on 1 ..... classroom teaching isn't my style
