# How to calculate these exercises in wolfram

Posted 10 years ago
 Hi guys, I want you to help me please as finding areas between curves and calculation of areas. Here's an exercise to chart, and not as it is in Wolfram. Calculate the area of the region bounded by the graphs of equations 2y ^ 2 = x + 4 and x = y ^ 2

 Hi David,I am not sure whether I fully understand your question, but this might help. First we can plot the curves> ContourPlot[{2 y^2 == x + 4, x == y^2}, {x, -4, 10}, {y, -4, 4}] which givesNow you see that the area between the curves will be infinite, because there is a difference of the curves right of the intersection points. For the next calculation I assume that you want the area of the finite bit for \$-4

 In[2]:= Integrate[ Boole[2 y^2 <= x + 4 && x <= y^2], {x, -\[Infinity], \[Infinity]}, {y, -\[Infinity], \ \[Infinity]}] Out[2]= 32/3
