Question

the value of cos theta increases as theta increases true or false justify your answer ​

Answer 1

Answer:

False

it will decrease

Step-by-step explanation:

$cos 0 = 1$

$cos 30 = \frac{\sqrt{3} }{2}$

$cos 45 = \frac{1}{\sqrt{2} }$

$cos 75 = \frac{1}{2}$

$cos 90 = 0$

We can see clearly that as theta increases cos theta decreases

Hope it is helpful

Answer 2

Answer:

false

Step-by-step explanation:

cos 45°=1/√2

cos 90°=0

as theta increases from 45° to 90° value of cos theta decreasas from 1/√2 to 0

therefore the statement prove that ,when cos theta increases theta decrease
