3x2=6x7=42
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
First, convert all the secants and cosecants to cosine and sine, respectively. Recall that
and
.
Thus:


Let's do the first part first: (Recall how to divide fractions)

For the second term:

So, all together: (same denominator; combine terms)

Note the numerator; it can be derived from the Pythagorean Identity:

Thus, we can substitute the numerator:

Everything simplifies to 1.
About 8,456.17849
Rounded: 8,456.18
A = ((6 + 7 + 6) . 8)/2
A = 19 . 4
A = 76
