Answer:
4 5/8 the answer you have is correct :)
Step-by-step explanation:
First, you want to make the mixed fraction into an improper fraction.
7 x 4 + 3 = 31 (31/4)
3 x 8 + 1 = 25 (25/8)
Now you want them both to have a common denominator.
31/4 x 2/2 = 62/8
Now you are ready to subtract!
62/8 - 25/8 = 37/8
Finally, convert 37/8 to a proper fraction.
37/8 = 4 5/8

<u>Answer </u><u>:</u><u>-</u></h3>
( 1 - cos²x ) secx
=> sin²x . secx
Here the rule ( rule 1 ) is the first trigonometric identity [ sin²A + cos²A = 1 ] by simplifying we have , [ 1 - cos²A = sin² ] . So here we substituted 1 - cos²x = sin²x .
=> sin²x [ 1/cosx ]
Here the rule ( rule 2 ) is secx = 1/cosx . So here we substituted secx = 1/cosx .
=> sinx [ sinx/cosx ]
Here the rule ( rule 3 ) is sin²x can be written as sinx . sinx , so we get sinx . sinx [ 1/cosx ] next by simplifying , sinx [ sinx/cosx ].
=> sinx tanx
Here the rule ( rule 4 ) is , in the above we got sinx/cosx and here we know that , sinx/cosx = tanx . So we have tan x .
I think the answer is $30 but I’m not entirely sure
