The values of sintheta(1), cos^(2)theta(...

The values of `sintheta_(1), cos^(2)theta_(2)` and `tan theta_(3)` are given as `0.5, -0.5` and `3` (not in order), for some angles `theta_(1), theta_(2)` and `theta_(3)`. Choose incorrect statement.

A

The value of `tan theta_(3)` could be `-(1)/(3)`

B

The value of `cos^(2)theta_(2)` can't be `-(1)/(3)`

C

The value of `sin theta_(1)` could be 3.

D

The value of `tan theta_(3)` can't be 3.

Text Solution

Verified by Experts

As `-1lesin theta_(1)lt1,0lecos^(2)theta_(2) let1` and `-oo lt tan theta_(3) le oo`
So only 1 and 2 are correct.
