Simplify:

`( CotA - tanA ) / ( CotA + tanA )`

Simplify: sqrt((1+cotA)/(1-cotA))

Prove that: cot2A + tanA= cotA - cot 2A

tanA +tanB + tanC = tanA tanB tanC if

What is the simplified value of (tanA)/(1-cotA)+(cotA)/(1-tanA)-(2)/(sin2A) ?

(cosecA - sinA)^2+(sec A-cosA)^2- (cotA - tanA)^2 is equal to : (cosecA - sinA)^2+(sec A-cosA)^2- (cotA - tanA)^2 का मान किसके बराबर है?

The value of (secA + tanA-1) (sec A -tanA+1) -2tanA is equal to

What is the simplified value of ((cosecA)/(cotA+tanA))^(2) ?

cosA(secA-cosA)(cotA+tanA)=?

Prove that: (tanA + tanB)/(cotA+cotB)=tanAtanB
