Find the value of : sec(cos^(-1)(2/3))

Find the value of : sec(cos^(-1)(2/3))

cos^(-1)((1)/(sqrt(2)))+sec^(-1)(-sqrt(2))

Evaluate: cos{sin^(-1)(-7/(25))} (ii) sec{cot^(-1)(-5/(12))} (iii) cot{sec^(-1)(-(13)/5)}

Evaluate: cos{sin^(-1)(-(7)/(25))}( ii) sec{cot^(-1)(-(5)/(12))}cot{sec^(-1)(-(13)/(5))}

If (sin^(-1)a)^(2)+(cos^(-1)b)^(2)+(sec^(-1)c)^(2)+(cosec^(-1)d)^(2)=(5pi)^(2)/2 , then the value of (sin^(-1)a)^(2)-(cos^(-1)b)^(2)+(sec^(-1)c)^(2)-(cosec^(-1)d)^(2) is equal to

cos^(-1)(1/(sqrt(2)))+sec^(-1)(-sqrt(2))=
