Answer:
5000
Step-by-step explanation:
Let's start with something that makes sense:
10 is 2 times larger than 5 because 5*2=10 or 10/5=2.
100 is 4 times larger than 25 because 25*4=100 or 100/25=4
Notice what's in bold. To find out how many times a larger number is compared to a smaller number, divide the larger number by the smaller number. Now, see attachment 1
Reduce terms: (sin x + sin 3x)/(cos x - cos 3x) =cos(2x)/sin (2x)
(sin x + sin 3x)/(cos x - cos 3x) = cot (2x)
The last line proves the identity (sin x + sin 3x)/(cos x - cos 3x) = cot (2x)
the length of the line would be 1 inch
Answer:
A, B, E, and F
Step-by-step explanation:
sinx and cosx are defined for all values of x. So, sin⁻¹x and cos⁻¹x are also defined for all values of x.
A and E are correct.
tanx is defined for all values of x.
However, tan(nπ) = 0 at when n is an integer. So, tan⁻¹(±nx) is undefined. However, tan⁻¹(-½x) is defined, because -½ is not an integer.
B and F are correct.
C and D are <em>wrong</em>. Both sec⁻¹x and csc⁻¹x are undefined when -1 < x < 1, and -½ is in this forbidden region.
