Trying to figure out how to find the length of a polar curve eq - r=7sin(theta + Pi/4). I do not know how to do this HELP

Question

bahrom7893 · Answer

what is the equation?
r = 7Sin(theta+Pi/4)
or
- r = 7Sin(theta+Pi/4) ?

r=

okay so..

bahrom7893 · Answer

$$Length = \int\limits_{a}^{b} \sqrt{r^2+(dr/d \theta)^2}d \theta$$

Now the hard part here is, finding the limits.. i forgot how to do that, let me graph this thing, see what it looks like..

bahrom7893 · Answer

still tryin to figure out limits...

bahrom7893 · Answer

do you know how to find limits? I've always been bad at polar stuff...

anonymous · Answer

no - this problem came from my College algebra/trig 400 class. Not  doing integration yet.

I think i know the limits, but sorry I can't solve this without integrating, never learned any other way of finding arclength..=(
