say true or false: sec theta =-2,theta lies in 4th quadrant
Answers
Answer:
False
Step-by-step explanation:
In 4th quadrant,cos and sec are positive.
value of sin,cosec,tan,cot are negative.
SOLUTION
TO CHECK
True / False below statement
If sec θ = - 2 then θ lies in 4th quadrant
EVALUATION
Here the given statement is
If sec θ = - 2 then θ lies in 4th quadrant
So sec θ is negative
We know that -
In 1st quadrant : All Trigonometric ratios are positive
In 2nd quadrant : sin and cosec is positive , rest of the Trigonometric ratios are negative
In 3rd quadrant : tan and cot is positive , rest of the Trigonometric ratios are negative
In 4th quadrant : cos and sec is positive , rest of the Trigonometric ratios are negative
Since sec θ is negative
So θ can not lie in 4th quadrant
Since in 4th quadrant sec is positive
FINAL ANSWER
Hence the statement is FALSE
