cos(2cos^(-1)(3)/(5))

Write the value of cos^(2)((1)/(2)cos^(-1)(3)/(5))

cos[2cos^(-1).(1)/(5)+sin^(-1).(1)/(5)] =

cos[2cos^(-1)((1)/(5))+sin^(-1)((1)/(5))] =

Evaluate : cos(2cos^-1(2/5))

Write the value of cos^2(1/2cos^(-1)3/5)

Write the value of cos^2(1/2cos^(-1)(3/5))

sin{2cos^(-1)((-3)/(5))}=

Evaluate: sin [2cos^(-1) ((-3)/(5))]

cos^(-1)((3)/(5))+cos^(-1)((4)/(5))=(pi)/(2)

If |z-25i|le15 , then |maximum arg(z) - minimum arg(z)| equals (A) (pi)/(2)+cos^(-1)((3)/(5)) (B) sin^(-1)((3)/(5))-cos^(-1)((3)/(5)) (C) 2cos^(-1)((4)/(5)) (D) 2cos^(-1)((1)/(5))
