Answer» tion:mark it as brainliest\begin{gathered}so \: here \: \\ secA + tanA =x \\ ie \: TAN \: A = x - SEC \: A\end{gathered} soheresecA+tanA=xietanA=x−secA \begin{gathered}so \: now \: using \\ 1 + tan ^{2} A = sec {}^{2} A \\ 1 + (x - sec \: A) {}^{2} = sec {}^{2} A \\ 1 + x {}^{2} + sec {}^{2} A - 2sec \: A.x = sec {}^{2} A \\ 1 + x {}^{2} - 2sec \: A.x = 0 \\ ie \: 1 + x {}^{2} = 2secA.x \\ sec \: A = 1 + x {}^{2} /2x \\ \\ \end{gathered} sonowusing1+tan 2 A=sec 2 A1+(x−secA) 2 =sec 2 A1+x 2 +sec 2 A−2secA.x=sec 2 A1+x 2 −2secA.x=0ie1+x 2 =2secA.xsecA=1+x 2 /2x \begin{gathered}THUS \: value \: of \: sec \: A \: (in \: TERMS \: of \: x) \: is \: 1 + x {}^{2} /2x \\ \end{gathered} |
