Evaluate : (i) 3 cos 80^(@) "cosec 10"^(@) + 2 sin 59^(@) sec 31^(@) (ii) (cos 70^(@))/(sin 20^(@)) + (cos 59^(@))/(sin 31^(@)) - 8 sin^(2) 30^(@) (iii) "cosec" (65^(@) + A) - sec(25^(@) - A)

What is the value of cosec (65^(@) + theta) - sec(25^(@) - theta) + tan^(2) 20^(@) - cosec^(2) 70^(@) ?

Prove that (i) sin(40^(@)-theta)-cos(50^(@)+theta)=0 (ii) sec(65^(@)+theta)-"cosec"(25^(@)-theta)=0

"cosec"(270^(@)-A)+"cosec"(90^(@)-A)+sec(90^(@)-A)+sec(270^(@)-A)=

"cosec" 15^(@) + sec 15^(@) =

What is the value of cosec(65^@+theta) -sec(25^@-theta)+tan^2 20^@- cosec^2 70^@ ? cosec(65^@+theta) -sec(25^@-theta)+tan^2 20^@- cosec^2 70^@ का मान क्या है ?
