I'm having trouble with this question as I'm sure how the do the problem when it involves the isosceles triangle. I be great if someone could possibly draw me a diagram and show me how to form the equation to use and evaluate the definite integral that is obtained from the intercepts that I already know to be the square root of 1/2 and -1/2.
Thanks a lot Chris L T521.
I managed to find A(x) but I found I made a mistake as I cancelled the ½ and the square for some reason so I only had A(x) as (2x^2-1)
I then found V but I just wasn't sure that it was equal to the other definite integral.
I found the answer 0.3771 to be the same evaluating either integral so I assume this is correct?
