If sinA- cosA=1 then find the value of 1/ sinA+cosA

1.	If sinA- cosA=1 then find the value of 1/ sinA+cosA
Answer» But is que ka answer 2√7/7 hi hai SinA - CosA=1So, SinA=1+CosAUpon Squaring on both sides,Sin square A = (1+CosA) squareSince Sin square A = (1 - CosA)(1+CosA),(1 - CosA)(1+CosA)=(1+CosA)(1+CosA)So, 1 - CosA = 1+CosA,2CosA=0So, CosA=0.So A=90 degreesSubstituting A=90 degrees in 1/sinA+cosA,We get 1/sinA+cosA = 1/1+0=1/1=1Therefore the answer is 1. But iska ans 2√7/7 hai Answer is 1+cosA
