cosec(cos^(-1)(3)/(5)+cos^(-1)(4)/(5))

Evaluate: sin(cos^(-1)(3)/(5)+csc^(-1)(13)/(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))

"cosec"[2 cot^(-1)(5) + cos^(-1)(4/5)] is equal to

If cos ^(-1)((3)/(5))-sin ^(-1)((4)/(5))=cos ^(-1) x, then x=

tan [sin ^(-1)((3)/(5))-cos ^(-1)(-(4)/(5))]=

Evaluate cos(sin^(-1)(4/5)+cos^(-1)(2/3))

If cos^(-1) ((x)/(5)) + "cosec"^(-1) ((5)/(4)) =ppi/2 then x=…….

If cos^(-1) ((x)/(5)) + "cosec"^(-1) ((5)/(4)) =ppi/2 then x=…….
