find the range of log_(2)((3sin x-4cos x+15)/(15))

int (cos x +2 sin x)/(3 cos x + 4 sin x)dx

Find the maximum and minimum of 3sin 2x+4 cos 2x+3

Let I=int_(0)^(oo)(cos x+4)/(3sin x+4cos x+25)dx and J=int_(0)^((pi)/(2))(sin x+3)/(3sin x+4cos x+25)dx If 25I=a pi+(b)/(n)(c)/(d) where a,b,c and d in N and (c)/(d) is not perfect square of a rational then find the value of (a+b+c+d)
