" 5."(2cos x)/(sqrt((4sin^(2)x+5)))

int (dx)/((4sin^(2)x+5cos^(2)x))=?

int (dx)/((4sin^(2)x+5cos^(2)x))=?

sin x+cos x=sqrt(2)sin5x

cos^(-1)((sin x+cos x)/(sqrt(2))),(pi)/(4) lt x lt (5pi)/4

Solve the equation: (4sqrt((cos x)/(2))-5-(sqrt(2))/(2))^(2)+sqrt(2)(4sqrt((cos x)/(2))-5-(sqrt(2))/(2))-(cos x)/(2)=0

int (sin ^ (2) x cos ^ (2) x) / ((sin ^ (5) x + cos ^ (3) x sin ^ (2) x + sin ^ (3) x cos ^ (2) x + cos ^ (5) x) ^ (2)) dx

Evaluate the following: int frac{cos x}{sqrt (sin^2 x - 2sin x +5)} dx
