dont get angry
I have seen some integration in add maths, was just voicing my humble opinion

haha wasnt getting angry, wrongly perceived man. it will have trigonometry in it.

 

[Faizan Muhammmad]

here this should solve it:
http://www.integral-calculator.com/#expr=(x^2)/(4-x^2)^0.5

you are supposed to press the go button

@FRENZYAMU here ,..

okay done.
first step replace x/2 with the substitution cosy
after all the cancellation u should get integeration of cos^2, now integerate it simply and in the end counter the substitution

@Mr.Smart this is a 2 mark question and is sooo long just because you have to figure out a right substitution, do u know where the question is from? midterm, final?

well i dont exactly know,, my friend just sent me this pic, so idk much bout it :/
thanks alot

 

[Mr.Smart]

hey @FRENZYAMU substitution dobara btao, kisko substitute krna hae? :/
u wrote x/2 with cos( y ) ,, but there is no x/2 in this function
its x^2
u r cnfusing me :/
