If tan θ =1and 0 ,

Home » Aptitude » Trigonometry » Question

If tan θ = 1 and 0 , < θ <
π , then the value of
cosec² θ - sec² θ is
√11 2 cosec² θ + sec² θ

tan θ =	1	; cotθ = √11
	√11

∴	cosec²θ - sec²θ
	cosec²θ + sec²θ

=	1 + cot²θ - (1 - tan²θ)
	1 + cot²θ + 1 + tan²θ

=	cot²θ - tan²θ
	cot²θ + tan²θ + 2

=		120	=	5
		144		6

If tan θ =		1	and 0 , < θ <	π	, then the value of	cosec² θ - sec² θ	is
		√11		2		cosec² θ + sec² θ
