Expert Answer:

Here, sin 60 + sin 30 = root(3)/2 + 1/2 = 1.73/2 + 1/2 = 0.865 + 0.5 = 1.365
Also, sin 90 = 1
Therefore, sin 60 + sin 30 is not equal to sin 90.
Your confusion is 1.365 is more than 1 and sin can not be more than 1.
So be careful, here 1.365 is not equal to any sine value but it the sum of two different sine values,
which may or may not be more than 1.
