Concept:

Trigonometric angles are used to represent the Trigonometric functions in an angle of a right-angled triangle to ratios of two side lengths.

Given:

We have,

Sin 16 × sin48 × sin 74 × sin42

Find:

We are asked to find the value of Sin 16 × sin48 × sin 74 × sin42.

Solution:

We have,

Sin 16 × sin48 × sin 74 × sin42

So,

Using the Trigonometric angles,

i.e.

Sin 16° = 0.275637

Sin 42° = 0.669131

Sin 48° = 0.743145

Sin 74° = 0.961262

So

Now,

putting values,

we get,

Sin 16 × sin48 × sin 74 × sin42

i.e.

= 0.275637 × 0.669131 × 0.743145 × 0.961262

On solving,

We get,

= 0.12315

i.e.

Sin 16 × sin48 × sin 74 × sin42 = 0.12315

Hence, the value of Sin16 × sin48 × sin 74 × sin42 of is 0.12315.
