1.	Prove that cot theta - tan theta =2 cosec^2 theta -1/sin theta cos theta
Answer» Step-by-step explanation: NTH TERM of an A.P (an) = PN + q To find: Common Difference (d) Proof: We know that, an = a + (n – 1)d ⇒ pn + q = a + (n – 1)d [GIVEN] ⇒ pn + q – a = (n – 1)d

Prove that cot theta - tan theta =2 cosec^2 theta -1/sin theta cos theta

Answer»

Step-by-step explanation:

NTH TERM of an A.P (an) = PN + q

To find: Common Difference (d)

Proof: We know that,

an = a + (n – 1)d

⇒ pn + q = a + (n – 1)d [GIVEN]

⇒ pn + q – a = (n – 1)d
