I have function y=x^5+x^8+ (cos(x))^3; I need to get random x; random y; and after that determine whether y below or above the given function. I tried a lot of version. but my code even doesnt work....plz help with this expressions ;( I am a begiiner in R -- View this message in context: http://r.789695.n4.nabble.com/area-under-the-curve-tp4649943.html Sent from the R help mailing list archive at Nabble.com.
I mean i need to put random x in equation in order to determine value y. i used runif....but it doesn work... y= (runif(0,1))^5+(runif(0,1))^8+((cos runif(0,1)))^3; (<=it doesnt work properly) now i have value y.... need to determine whether y is above or below my function..... so after that y1=runif(1,0,3); -- View this message in context: http://r.789695.n4.nabble.com/area-under-the-curve-tp4649943p4649944.html Sent from the R help mailing list archive at Nabble.com.
