Answer:
The same line
Step-by-step explanation:
Recall that if two graphs, representing a system of equations has infinite solutions, this means that point on one graph must coincide with a corresponding point on the other graph. The only way that this can happen is if both graphs coincide with each other perfectly, which is to say that they are the same line.
Answer:
Therefore the correct option is first one
![\dfrac{\pi}{4}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cpi%7D%7B4%7D)
Step-by-step explanation:
Given:
![\arcsin (\dfrac{\sqrt{2} }{2})](https://tex.z-dn.net/?f=%5Carcsin%20%28%5Cdfrac%7B%5Csqrt%7B2%7D%20%7D%7B2%7D%29)
To Find:
![\arcsin (\dfrac{\sqrt{2} }{2})=?](https://tex.z-dn.net/?f=%5Carcsin%20%28%5Cdfrac%7B%5Csqrt%7B2%7D%20%7D%7B2%7D%29%3D%3F)
Solution:
The arcsin function is the inverse of the sine function.
It returns the angle whose sine is a given number.
So,
![\sin \dfrac{\pi}{4}=\dfrac{1}{\sqrt{2}}](https://tex.z-dn.net/?f=%5Csin%20%5Cdfrac%7B%5Cpi%7D%7B4%7D%3D%5Cdfrac%7B1%7D%7B%5Csqrt%7B2%7D%7D)
Means: The sine of
radian is
∴
Means: The angle whose sin is
is
radian.
Therefore the correct option is first one
