Question

hii frnds....
sin60cos30-cos60sin30 = sin30
solve this question.....

Answer 1

Hey !!!

sin60° = √3/2

cos30° = √3/2

cos60° = 1/2

sin30° = 1/2

we know about that all formula just these formula .

From LHS

√3/2*√3/2* - 1/2*1/2

=> 3/4 - 1/4

=> 3 - 1/4

=> 2/4 = 1/2

from RHS

sin30° = 1/2 verified here

LHS = RHS

Answer 2

sin60cos30-cos60sin30=sin30
let put their values
sin60=root3/2
cos30=root3/2
cos60=1/2
sin30=1/2
LHS
root3/2×root3/2-1/2×1/2
=3/4-1/4
=3-1/4
=2/4
=1/2
and the value of sin30=1/2
RHS=sin30

LHS=RHS
hence proved
hope it helps you
