Question

sin(π÷2)+cos(π÷4)+1÷tan(π÷4)

Answer 1

hello users ...

solution:-
we know that:
the value of 
sin π/2 = sin 90° = 1 
And
cos π/4 = cos 45° = 1/ √2
And
tan π/4 = tan 45° = 1 

Now 
putting all the values;
we get
sin π/2 + cos π/4 + 1 / tan π/4

= 1 + 1/ √2 + 1 / 1 
= 1 + 1/√2 + 1 
= 2 + 1/ √2 
= ( 2√2 + 1 ) / √2 Answer 

# hope it helps :)
