C

y3ds, C: x = t3, y = t, 0 ≤ t ≤ 3

please follow this straightforward approach:
1) Select Vector Calculus under F6
2) F2 2 Line Integral and enter

f=y^3 as integrand
variables [x,y]
Now lets enter the path next:
[t^3,t]
variable : t
bounds : [0,3]

Press ENTER a few times and VOILA !!
Easy as pie.

Customer review of Calculus Made Easy

Calculus Made Easy is awesome, im taking Calc 1 right now and it helps a lot with derivatives and how to do it step by step! Makes it clearer how to use differentiation rules to obtain the right answers! Its also great that it does not just one, but a couple of laws and rules applicable in solving the problem, nothing short of being helpful program!

Thank you!

y − cos y, x sin y

, C is the circle (x − 6)2 + (y + 2)2 = 16 oriented clockwise

ANSWER:
Please do this: select F6 Vector Calculus , F2 8 : and enter as follows

[M,N]= [y-cos(y),x*sin(y)]

solve (x − 6)2 + (y + 2)2 = 16

(y + 2)2 = 16 – (x − 6)2

y = + – sqrt (16 – (x − 6)2) – 2

thus
y1,y2 =[ – sqrt
(16
(x  6)2 )
– 2 ,   sqrt (16(x  6)2 )
– 2 ]

we have a circle centered at [6,2] of radius 4
thus x varies from 2 to 10

x1 , x2 = [2,10]

Voila!!!

Ti Connect software update

Wednesday, December 9th, 2015

Tip of the day:

In addition to the familiar TI Connect software – used to transfer TI89 apps from a computer to a TI89 – there now exists TI Connect CE software that only works for TI84 calculators.

So if you mistakenly try to transfer ti89 apps using the CE version you will run into transfer errors and don’t know why.

To avoid these transfer errors make sure to download the TI Connect software for TI89s at http://ti89.com/ticonnect.php or at education.ti.com .
