(1+tan theta+sec theta)(1+cot theta-cosec theta) = 2 | (1+tan A+sec A)(1+cot a-cosec A)=2
Q: Choose the correct option. Justify your choice.
(1 + tan θ + sec θ) (1 + cot θ – cosec θ) =
(A) 0 (B) 1 (C) 2 (D) –1
Hint 💡
tan A = sin A/cos A
sec A=1/cos A
cot A= cos A/sin A
cosec A = 1/sin A
(a+b)(a-b)=a^2-b^2
(a+b)^2=a^2+b^2+2ab
