Question

1-cos^2A÷1+sinA=sinA

Answer 1

Hi !

Solution :- From LHS

= 1 - cos²A /1+sinA

= sin²A /sinA [°•° 1 - cos²A= sin²A]

= sinA

Since, lHS = RHS Prooved ✔

Answer 2

Answer:Hey friend (^_^)

Here is your answer :

1-[cos²A/(1+sinA)]=sinA

LHS :

=1-[cos²A/(1+sinA)]

[USING cos²A+sin²A=1]

=1-[(1-sin²A) /(1+sinA)]

[USING a²-b²=(a+b)(a-b) ]

=1-[(1+sinA)×(1-sinA)/(1+sinA)]

=1-(1-sinA)

=1-1+sinA

=sinA

=RHS
