If `secA-tanA=(a+1)/(a-1)` then `cosA` is

If secA + tanA =a, then the value of cosA is यदि secA + tanA =a हो, तो cosA का मान क्या होगा?

If secA+tanA=1/3 , then secA-tanA = …………..

Prove that (tanA+secA-1)/(tanA-secA+1)=(1+sinA)/(cosA) Thinking Process : Here, use the formula i.e., sec^(2)A-tan^(2)A=1anda^(2)-b^(2)=(a+b)(a-b) to solve the above problems.

( secA+tanA )( 1−sinA )= (a)secA (b) sinA (c) cosec A (d) cosA

(tanA)/(1+secA) - (tanA)/(1-secA) = 2cosecA

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

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

If sinA=1/3 then cosA. cosecA+tanA.secA=

Prove that (tanA)/(1+secA) - (tanA)/(1-secA) = 2cosecA
