The exact value of sin 15° is
.
Solution:
45 – 30 = 15
sin 15° can be written as sin (45° – 30°).
Using trigonometric difference formula:
sin(A – B) = sin A cos B – cos A sin B
sin (45° – 30°) = sin 45° cos 30° – cos 45° sin 30°
The value of sin 45° = 
The value of cos 30° = 
The value of cos 45° = 
The value of sin 30° = 
Substitute these values, we get





Hence the exact value of sin 15° is
.
Answer:
The maximum error in calculating the surface area of the box is 152 square cm.
Step-by-step explanation:
We are given the following information in the question:
The dimensions of a closed rectangular box are measured as 80 cm, 60 cm, 50 cm, respectively.
Possible error = 0.2 cm
Surface area of rectangular box =

where l, b and h are the length, breadth and height of the rectangular box respectively.
Change in area =

Putting the values, we get,
Change in area =

The maximum error in calculating the surface area of the box is 152 square cm.
