Question

can you guys answer fast ​

Answer 1

Answer:

it is a very hard question you can

Answer 2

Answer:

let's assume a=45°

then sin a =1/√2 and cos a=1/√2

adding we get,

2/√2

2*√2/√2*√2

2√2/2

√2

Now, squaring both sides we get,

(√2)^2=2

and (1)^2= 1

therefore, LHS>

RHS

Step-by-step explanation:

HENCE PROVED SIN A+COS A >1
