Question

How many possible values for y are there where y = cos^-1 0?

Answer 1

Answer:

1

Step-by-step explanation:

Just took the quiz

Answer 2

Possible values for y are infinite

Further explanation

Trigonometry is the science of mathematics that studies the relationship between sides and angles in triangles

Given special angles of trigonometric functions, for example

$\displaystyle sin~0=0\\\\cos~30=\frac{1}{2}\sqrt{3}\\\\tan~45=1\\\\sec~45=\sqrt{2}\\\\etc.$

In the trigonometric function equation y = cos⁻¹ 0, then the value of y can be determined:

y = cos⁻¹0

y = arc cos 0

cos y = 0

Then the value of y :

$\displaystyle \frac{\pi }{2},\frac{3}{2}\pi,\frac{5}{2}\pi , etc$

Or can be formulated :

$\displaystyle y=\frac{\pi }{2} (2n-1)$ ⇒ y: arithmetic sequence

So there are infinite values for y
