Question

Is sin(π-a) = cos a?​

Answer 1

Answer:

sin(π-a) is not equals to cos a

Step-by-step explanation:

LHS

sin(π-a)

sin(22/7-a)

cos( 90 - (22/7-a) )

cos( 90 - 22/7 + a )

cos(608/7 + a)

RHS

cos a

form RHS and LHS we get to know that

cos(608/7 + a)    _    cos a

608/7 + a   _  a                                                   .....................removing cos

so here ,   608/7 + a  $\neq$  a

so   sin(π-a)  $\neq$ cos a

so  sin(π-a) is not equals to cos a
