Re: [R] area under the curve

I mean i need to put random x in equation in order to determine value y. i used runifbut 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=r

[R] area under the curve

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 workplz help with this expressions ;( I am a begiiner in R -- View this message in context: http:

[R] Help plz to fix it

I have an array of probabilitiesit is p. So if user types x=1 then probability is p1=1/10. If user types x=2 it means that p2= p1+p2 if user types x=3 it means that p3=p1+p2+p3and so on. So i created a code. but it doesnt work properly. Help me plz to fix it) Thank u in advance. psidp
