Question

When x increases from 0 to π/2 , what will happen to the value of cos x

Answer 1

Answer:

The value of cos x will decrease

cos 0 = 1

cos π/2 = 0

So it decreases

Answer 2

If we increase the value of x from 0 to $\frac{\pi }{2}$  then cos x will decrease

Step-by-step explanation:

It is given that when x is increases from 0 to $\frac{\pi }{2}$ then what will happen to cos x

From the bellow figure we can see that value of cos x is maximum when value of x is 0

And it is decreasing in nature and finally at $x=\frac{\pi }{2}$ value of cox become 0

So if we increase the value of x from  0 to $\frac{\pi }{2}$ then value of cos will decrease.

From example cos 0 = 1 and if we increase the value of x then cos 45° = 0.707 and if we again increase the value of x then cos 90° = 0

So if we increase the value of x then cos x will decrease
