Hello all, I searched the web for this answer, could not find it, as such i turn to you all smart people. I have read the thread
Cubic equation from 4 coordinates
However i have no idea what to do, if someone can help me before the end of April would be appreciated.
Ok the question is:
*graph* coordinates that can be known, (0,0) (1,8) (2,6) (3,0) (4,-4) (5,0) and (6,18)
Now the actual question is to find accurately the area enclosed by this curve and the x-axis, but to do it accurately, one would have to use definite integral. However i have used the Trapezium Method and the Triangle area method to kinda get an area, but the question after this one requires this one to be dead accurate
i have battled with it for some time; I have nooooo cooking clue of how to do this....
Sorry for double posting/ spamming (if you really can call it that) didnt know it was against rules.
Well yes it is actualy a cubic function, we're in a public school so what do you expect from questions, they only hint at what it is awell
thank you everyone
I have a massivly COOOOL graphics calculator that did it for me, like i was so stressing and then the teachers like " oh and this is how you get the formula for a cubic"
Icemanfan, how did you find that equation? because i wanna know how you did it
Captian Black your tooo smart, ive got a physics teacher like you knows everything in the world i rekon :P
awell thank you all
