यदि `(sinx)^(y)=(cosy)^(x)` हो, तो सिद्ध कीजिए कि-
`!=(logcosy-ycotx)/(logsinx+xtany)`

If (sinx)^y=(cosy)^x ,p rov et h a t(dy)/(dx)=(logcosy-ycotx)/(logsinx+xtany)

If (sin"x")^y=(cos"y")^x , prove that (dy)/(dx)=(logcosy-ycotx)/(logsinx+xtany)

If (sinx)^y=(cosy)^x , prove that (dy)/(dx)=(logcosy-ycotx)/(logsinx+xtany)

If (sin"x")^y=x+y ,p rov et h a t(dy)/(dx)=(1-(x+y)ycotx)/((x+y)logsinx-1)

यदि triangleABC में (If इन triangleABC), a = (1)/(sqrt(6)-sqrt(2)), b = (1)/(sqrt(6)+sqrt(2)), C = 60^(@) तो सिद्ध कीजिए कि (Prove that) c = (sqrt(4))/(2) .

(sinx-siny)/(cosx+cosy)=tan(x-y)/(2)

यदि x^(2)+2=0 हो तो x का मान होगा-

If sinx siny = 3 (cosy - cos x) then (sin3x)/(sin3y) =

यदि "(3+4i)/(4-5i)=a+ib" हो,तो "*a'" और ' "b" ज्ञात कीजिए। "

prove (sinx-siny)/(cosx+cosy)=tan(x-y)/2
