integral(1/sqrt(16-x^2))dx



using trig substitution

sin(-)=x/4
4sin(-)=x

sqrt(4^2-x^2)=4cos(-)

dx = d/dx(x)
dx = d/dx(4sin(-))
dx = 4cos(-)d(-)

substitute to original equation:

integral((1/4cos(-))(4cos(-)d(-)))
= integral (1 d(-))

integrate it and you get (-)+C.

now since sin(-)=x/4
(-) = arcsin(x/4)

therefore (-)+C = arcsin(x/4)+C

Fine, I'll post dat problematic program ;-;

(to xeda: it's the label "ETURN that sometimes freezes. Pic1 and Pic0 stays archived, and make sure you choose "new" first before selecting "load")

All right. So here's the screenshot of it so far



The battle system was working, but now it doesn't ;-; I'm still figuring out what went wrong.

It seems like I still won't be able to make it into contest (took too much time dealing with my calc issue). Only if I had more time to use computer, I would've done it though. Oh well, at least I tried. However, do expect a demo around next week though.

Argh ERR:? On jumping to another program is back. Xeda said she doesn't have any problem in her calc so idk what the problem is.

Finally figured out what went wrong with the routine. Apparently new grammer hates the space between maths and prefer colons more. So scrolling works again.

Xeda do u remember my rol3 port? It uses a same routine. I don't think I use specific command though. Just reading data and conditionals.

No, I just have to optimize more but I don't want to think about it until I'm pretty much done with the program. (The code is VERY long)
