<span>The answer is true
Let's imagine that we have the following function function:
</span> $y = x ^ 2 
$
<span>We have to:
Independent variable: x
Dependent variable: y
For x = -1:
</span> $y = (- 1) ^ 2 = 1 
$
<span> For x = 1:
</span> $y = (1) ^ 2 = 1 
$
<span> We observe that the independent variable can only obtain one result.

If sec theta = - √30 / 3, find cos theta.<br> if sin(-theta) = -0.97, find cos (π/2 - theta).

Cloud [144]

Step-by-step explanation:

$\cos \theta = \frac{1}{ \sec\theta } = - \frac{3}{ \sqrt{30} } = - \frac{3 \sqrt{30} }{30} = - \frac{ \sqrt{30} }{10}$

$\cos( \frac{\pi}{2} - \theta )= \cos \frac{\pi}{2} \cos \theta + \sin \frac{\pi}{2} \sin \theta$

Note that

$\sin( - \theta) = - \sin \theta$

$\cos \frac{\pi}{2} = 0 \: \: \: \: \: \sin \frac{\pi}{2} = 1$

Therefore,

$\cos( \frac{\pi}{2} - \theta ) = 0.97$
