`int (dx)/(5+4cosx)=atan^(-1)(btan(x/2))+c` then

int dx/(5 + 4 cosx)

If int(dx)/(5-4cosx)=Atan^(-1)(Btanx//2)+C , then

int(dx)/(5+4cosx)=atan^(-1)(b" tan"(x)/(2))+C , then a) a=(2)/(3),b=-1/3 b) a=2/3,b=1/3 c) a=-2/3,b=1/3 d) a=-2/3,b=-1/3

If int(dx)/(5+4cosx)=ktan^(-1)(mtan""(x)/(2))+c , then

If int(dx)/(5+4cosx)=ktan^(-1)(mtan""(x)/(2))+c , then

Evaluate int(dx)/(5+4cosx)= a tan^(-1) (b t a n (x/2))+C , then

int dx/(4+5cosx) =

int(dx)/(5+4cosx)=lambdatan^(-1)(mtan.(x)/(2))+C then
