Our basis for this equality is the pythagorean theorems of trigonometry. There are three equations for the pythagorean theorems. These are:
sin²x + cos²x =1
1 + tan²x = sec² x
1 + cot² x = csc² x
These are all derived from circle geometry on the cartesian plane. Now, the useful trigonometric property to be used is the third one. Rearranging this, we come up with
cot²x - csc²x = -1
This coincided with the given equation. Therefore, this is true. This is because it is already established from the pythagorean theorems.
Hello!
Half dollar = 0.50 cents
Quarter = 0.25 cents
20 ÷ 2 = 10
160 ÷ 4 = 40 br />
40 + 10 = 50

Answer:
The 2nd answer: y = 1/2x
Step-by-step explanation:
2 x 1/2= 1 and if you do 1/2 times x you'll see it works. Hope this helps!
