Question

Evaluate each of the following sin 60 cos 30° + cos 60° sin 30°

Answer 1

SOLUTION :

Given :  

sin 60° cos 30°  + cos 60° sin 30°                                                                                        

 = √3/2 × √3/2 + ½ × 1/2

= ¾ + 1/4  

= (3 + 1) / 4

[By taking L.C.M]

= 4/4 = 1

sin 60° cos 30°  + cos 60° sin 30° = 1

[sin 60° = √3/2 , sin 30° = 1/2

cos 30°= √3/2 , cos 60° = ½]

Hence, sin 60° cos 30°  + cos 60° sin 30° = 1
