Answer:
The value of SecФ is
.
Step-by-step explanation:
Given as for trigonometric function :
tan²Ф = 
Or, tanФ = 
∵ tanФ = 
So,
= 
So, Hypotenuse² = perpendicular² + base²
or, Hypotenuse² = (
)² + (
)²
Or, Hypotenuse² = 3 + 8 = 11
Or, Hypotenuse = (
)
Now SecФ = 
or, SecФ =
= 
<u>Second Method</u>
Sec²Ф - tan²Ф = 1
Or, Sec²Ф = 1 + tan²Ф
or, Sec²Ф = 1 + 
Or, Sec²Ф = 
Or, SecФ = 
Hence The value of SecФ is
. Answer

Answer:
(3a + 2b)3
Step-by-step explanation:
STEP
1 :
Equation at the end of step 1
(((27•(a3))+((54•(a2))•b))+(36a•(b2)))+23b3
Step 2:
(((27•(a3))+((54•(a2))•b))+(22•32ab2))+23b3
Step 3:
(((27•(a3))+((2•33a2)•b))+(22•32ab2))+23b3
Step 4:
((33a3 + (2•33a2b)) + (22•32ab2)) + 23b3
Step 5:
Factoring: 27a3+54a2b+36ab2+8b3
