" 13."sin2x*sqrt(a^(2)-cos^(2)x)

If x in(0,(pi)/(2)), thenshowthat(d)/(dx)cos^(-1){(7)/(2)(1+cos2x)+(sqrt(sin^(2)x-48cos^(2)x))sin x}=1+(7sin x)/(sqrt(sin^(2)-48cos^(2)x))

Solve the inequality sin2x>sqrt(2)sin^(2)x+(2-sqrt(2))cos^(2)x

sqrt(sin 2x) cos 2x

sqrt(sin 2x) cos 2x

Evaluate: int(sin2x)/(sqrt(cos^(4)x-sin^(2)x+2))dx

Solve the inequality sin2x gtsqrt(2)sin^2x+(2-sqrt(2))cos^2x

Solve the inequality sin2x gtsqrt(2)sin^2x+(2-sqrt(2))cos^2x

Solve the inequality sin2x gtsqrt(2)sin^2x+(2-sqrt(2))cos^2x

Solve the inequality sin2x gtsqrt(2)sin^2x+(2-sqrt(2))cos^2x
