Answer 2

Ответ:

0.5

Пошаговое объяснение:

$sin 63 cos 33-sin 33 cos 63 = sin(63-33)=sin 30 = 0.5$

Answer 3

It seems like you're trying to simplify a trigonometric expression. Let's work through it step by step.

The expression you've given is:

sin(63°)cos(63°) - sin(33°)cos(63°)

We can use the trigonometric identity that states:

sin(A)cos(B) - sin(B)cos(A) = sin(A - B)

Applying this identity to your expression, where A = 63° and B = 33°:

sin(63°)cos(63°) - sin(33°)cos(63°) = sin(63° - 33°)

Now, calculate the angle difference:

63° - 33° = 30°

So, the simplified expression is:

sin(30°)

Since the sine of 30° is 0.5, the final simplified expression is:

0.5
