MCQ
True or False

The value of cos θ increases as θ increases

• True

• False

#### Solution

cos 0° = 1

cos 30^@ =  sqrt3/2 = 0.866

cos 45^@ =  1/sqrt2  = 0.707

cos 60^@ =  1/2 = 0.5

cos90° = 0

It can be observed that the value of cos θ does not increase in the interval of 0° < θ < 90°.

Hence, the given statement is false.

Is there an error in this question or solution?
