Question

if sinA+cosA=1 then show that sinA-cosA=1​

Answer 1

Answer: hope it helps

Step-by-step explanation:

Answer 2

Step-by-step explanation:

sinA+cosA=1

squaring on both sides

sin^2A+cos^2A+2sinAcosA=1

1+2sinAcosA=1

2sinAcosA=0......1

now

sinA-cosA

square ans root

√sin^2A+cos^A-2sinAcosA

√1-2sinAcosA

substituting eq1

√1 = 1
