				   integrate sin2x/sin5xsin3x

6 years ago


Answers : (1)


sin2x can be written as sin(5x-3x)=sin5xcos3x-sin3xcos5x



  integral of cot3x-cot5x=logsin3x/3  -  logsin5x/5 + c

                                  =log{(sin3x)^1/3/(sin5x)^1/5} + c

I am looking for the solution for following integral dx/x.(x^2n-a^2n)^1/2
Write I = dx/x.(x^2n-a^2n)^1/2 = dx/x.(x^n + a^n)^1/2.(x^n – a^n)^1/2 = A/x + B/(x^n + a^n) + C/(x^n - a^n) Solve it by partially no. n is actually pi in image check it again plz.

Find the value of limit x tends to zero |x| ^[cosx]
tHE answer should be zero itself. As no determinancy forms here. Range of cosx is [-1,1] which is a constant fixed number. Therefore power of zero as anythng constant wiould be zero.

If sinx+siny=a and cosx+cosy=2a what is the value of cos(x-y) ?
We know that cos(x-y) = cosx.cosy+sinx.siny... So just substitute the given values in the above equation... We get cos(x-y)=2a+a =3a
