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:
It would take you 9 hours
Step-by-step explanation:
Speed (s) = Distance (d) / Time (t)
given that; Speed = 42 miles/hour
Distance = 361 miles
42 miles/hour = 361 miles / Time (t)
Time (t) * 42 miles/hour = 361 miles
Time (t) = 361 miles / 42 miles/hour
Time (t) = 8.59 hours
≈ 9 hours (to the nearest hour)
9/8 or 1 1/8
