Step-by-step explanation:
squaring on both sides
(sin A +cos A)²=(1)²
sin²A+cos²A+2sinA.cosA=1
1+2sinA.cosA=1
2sinA.cosA=0
sinA.cosA=0

Answer:
SinA + cosA = 1
Squaring both the sides
sin^2A + cos^2A +2sinAcosA = 1^2
1 + 2sinAcosA = 1 ------sin^2A + cos^2A = 1
2sinAcosA = 0
sinA×cosA = 0
Hope it helps....
