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

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

Express the value of "cosec"("cos"^(-1) 3/5 +"cos"^(-1) 4/5) in simplest form.

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))

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

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

sin^(-1)""((3)/(5))+"cosec"^(-1)""((5)/(4))

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

Evaluate: (i) tan {cos^(-1)(-(7)/(25))}_( (ii) )csc{cot^(-1)(-(12)/(5))}cos{tan^(-1)(-(3)/(4))}

Evaluate: sin{tan^(-1)((7)/(24))}( ii) cos{cot^(-1)((5)/(12))}csc{cot^(-1)((4)/(3))}
