<u>Answer and explanation</u>
(1+sinθ)(1-sinθ)=cos²θ
We are to prove that the left hand side is equal to the right hand side.
(1+sinθ)(1-sinθ) = 1(1-sinθ) + sinθ(1-sinθ)
= 1 - sinθ + sinθ - sin²θ
= 1 - sin²θ
From the trigonometric identity sin²θ + cos²θ = 1,
1 - sin²θ = cos²θ
An integer is a positive or negative whole number.
-54/6 = - 9 ....integer
45/9 = 5...integer
-65.72....not an integer because it has a decimal...it is not a whole number
3/4 = 0.75.....not an integer because it is not a whole number
36....integer
I’m gonna say put in the calculator 2x the hams age and then put -12 -5.
What you want to do is take 9 and multiply 9 by itself 5 times as shown (9*9*9*9*9) and you get 59049 then you take that number and divide it by 2 so 59049/2 is 29524.5
