Question

If sin A - cosA=0 then, prove that TanA=1 .​

Answer 1

Step-by-step explanation:

sina-cosa = 0 then Sina and cosa are equal and when we devide same number it gives 1 and tana is the divide of Sina/ cosa then it is proved

Answer 2

Step-by-step explanation:

Answer:

sinA - cosA = 0

=>sinA = cosA

=>sinA = 1 × cosA

=>p/h = 1 × b/h

=> p/h × h/b = 1

=> p/b = 1

=> tanA = 1 hence proved
