I have this line of code in an study on c++ pointers with functions and arrays but i don't understand it. can anyone provide a real basic example on what this does? My guess is that it is an array containing pointers which point to pointers that point to functions with return type of int?
2 AnswersProgramming & Design1 decade agodistance traveled by point p on a curve?
Consider the parametric curve given by the equations
x(t) = t^2 +14 t +3
y(t) = t^2 +14 t - 12
How many units of distance are covered by the point P(t) = (x(t),y(t)) between t=0, and t=8 ?
1 AnswerEngineering1 decade agoFind the area of an elipse with the given parametric equation.?
This seems to be an easy problem but everything i try is wrong...... the given equations are x=9cos@ and y=21sin@ where @ +theta. How do i find the area of the elipse thanks.

1 AnswerMathematics1 decade agoI hate math help pls........how do i solve the integral from 0-pi/4 of sin(2x)sin(x)dx?
I tried to work this out by setting u = to sin(x) then du was = to cos(x).........my final answer was sqrt(2)/3 but this was not right......
2 AnswersMathematics1 decade agol'hospital's rule, help with limit pls as x approaches inf (14x/[14x+7])^3x?
i thought i did this right but i guess its not right. i first rewrote the finction as 14x^3x over (14x+7)^3x i then multiplied both the top and bottom by ln. so this should allow me to move the 3x to the front and thus the 3x on bottom and top should cancle out. i then took the derivate of the top and bottom, simplified and i got one. but it wasn't right where did i mess up? thanks
