If tan theta = - (4)/(3), then sin theta...

If `tan theta = - (4)/(3)`, then sin `theta` is

`-4/5" but not "4/5`

`-4/5or4/5`

`4/5" but not "-4/5`

None of these

Text Solution

Verified by Experts

The correct Answer is:

`tantheta=(-4)/3`
`rArr theta in2nd` quadrant or 4th eqyadrant
`rArr sintheta =pm4//5`
If `theta in 2nd` equadrant, `sintheta=4//5`
If `theta` in 4th quadrant, `sintheta=-4//5`
