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.
Answer:
60m^2-10m
Step-by-step explanation:
I did the math
Volume of cylinder is π(2/2)²(4)=4πcc. Number of capsules=4π/3.5=3.59 capsules, so he will need about 4 capsules to fill the cylinder.
The answer is 10.55 l hope this helps
Answer:
answer≤27
Step-by-step explanation:
then the answer for x could be -4 or lower so -4+31 is 27 so the answer would be any number less than or equal to 27
