If tan θ + cot θ = 2, then the value of tan²θ + cot²θ is
A)2 B)1 C)√2 D)0
Read Solution (Total 2)
-
- A) 2
Solution:-
tan a + cot a= 2
sq. both side
tan2 a +cot2 a+2tan a* cot a=4
tan2 a +cot2 a+2=4
tan2 a +cot2 a=2 - 4 years agoHelpfull: Yes(0) No(0)
- This will only possible when theta = 45
So tan^2(45)+cot^2(45)=2 - 4 years agoHelpfull: Yes(0) No(0)
