Question

EVALUTE :-
sin 60 degree cos 30 degree + sin 30 degree cos 60 degree .


DO IT FAST PLZ !!!!


TOO MUCH URGENT....

Answer 1

=> sin60.cos30 + sin30.cos60

using trigonometric identity

=> sinA.cosB + cosAsinB = sin(A+B)

then

=> sin60.cos30 + cos60.sin30

=> sin(60+30)

=> sin90 = 1

Answer 2

Hey !!! ^_^

Here is your ans

AS we know the value of ,

Sin60° = √3/2 , Cos30° = √3/2 , Sin30° = 1/2 and Cos60° = 1/2

Now evaluate them in

Sin60° . Cos30° + Sin 30° .Cos 60°

√3/2 × √3/2 + 1/2 × 1/2

3/4 + 1/4

(3 + 1)/4

4/4
