Answer:
The Pythagorean identity states that
Using that we can rewrite the left denominator as:
Which can be factored as
The numerator we can expand as:
On the right hand side, let's multply numerator and denominator with (1 - sin t):
The total formula then becomes:
There you go... left and right are equal.
Step-by-step explanation:
Using functions, the input is x, the output is y.
<u>Break down the problem:</u>
The output (y) is (equals) one-fourth (1/4) of the input (x)
y equals 1/4 of x
If a₁ = 5 and , then
a₂ = a₁ - 3 = 5 - 3 = 2
a₃ = a₂ - 3 = 2 - 3 = -1
a₄ = a₃ - 3 = -1 - 3 = -4
a₅ = a₄ - 3 = -4 - 3 = -7
a₆ = a₅ - 3 = -7 - 3 = -10
