Evaluate ∬ √(4x^2-y^2) dxdy where E is the region bounded by the lines y=0,y=x and x=1. DOUBLE INTEGRALS #double integral



PROBLEM  :

Evaluate ∬ √(4x^2-y^2) dxdy where E is the region bounded by the lines y=0,y=x and x=1.

SOLUTION : 




 



 *   Evaluate ∬ f(x,y) dxdy where f(x,y)= (2y-1)/ x+1 , and E is the region bounded by x=0,y=0, y=2x-        4.

 *   Change the order of integration and hence show that ∬dx dy/[ ( 1+e^y) √(1-x^2-y^2)]   = (𝝿 /2)                    log(2e/(1+e) where x-0 to x=1 and y=0 to y=√(1-x^2)

 *   In the integral ∬ (4-y) dydx, change the order of integration and evaluate the integral where x=2 to            x=4 and y=4/x to y=(20-4x)/(8-x)

 *  Sketch the region of integration and evaluate ∬ xsiny dydx where x=0 to x=𝛑 and y-0 to y=x.

 *  Sketch the region of integration and write an equivalent double integral with the order of integration

     reversed for ∬ 3y dxdy where y=0 to y=1 and x= -√(1-y^2) to y=√(1-y ^2).

 *  Evaluate  ∬f(x,y)dxdy , where f(x,y)=x2+y2 and E={(x,y)/y=x2,x=2,y=1}   

 *  Evaluate ∬ xydxdy where E is the region bounded by xy=1,y=0,y=x,x=2.

sin30=1/2 what it means? 🤔 #sin30, #trigonometry

   we know sin30= 1/2. what it means ?   🤔        In a right triangle if the sine of  angle  30  = 1/2   means that the length of hypotenuse is always double the length of opposite side. i.e. if we take 6cm as length of opposite side then length of hypotenuse is 12 cm if we take 100 cm as length of opposite side then the length of hypotenuse is 200 cm etc.                      If any one has any doubts in trigonometry or any mathematic concern topics please ask in the comment section .Also anybody of you want to give me friendly suggestions  post in the comment section. * what is dimension of an object? * 4th dimensional object Hypercube . * what is angle?   Page navigation #sin30 #= #1/2 #what #it #means #?  #maths #mathematics # trigonometry  People also search for Iit mathematics  books IIT Mathematics  Questions Iit mathematics  ...
