Fill ..........=`cosA/sinA`

If (sinA+cosA)/(cosA)=17/12 , then the value of (1-cosA)/(sinA) is: यदि (sinA+cosA)/(cosA)=17/12 ,है, तो (1-cosA)/(sinA) का मान क्या होगा ?

Prove that: cotA/2-tanA/2=(cosA/2)/(sinA/2)-(sinA/2)/(cosA/2) =(cos^(2)A/2-sin^(2)A/2)/(sinA/2cosA/2) =cosA/(1/2.(2sinA/2cosA/2)) =(2cosA)/(sinA)=2cotA = RHS. Hence Proved.

Consider the following 1. (cosA)/(1-tanA)+(sinA)/(1-cotA)=sinA+cosA 2. (1-sinA-cosA)^2=2(1-sinA)(1+cosA) Which of the above is/are identity/identities?

Prove that : (i) (1-cosA)/(sinA)=(sinA)/(1+cosA) (ii) (costheta)/(1-sintheta)=(1+sintheta)/(costheta)

Find the value of ((cosA+cosB)/(sinA-sinB))^(n)+((sinA+sinB)/(cosA-cosB))^(n) (where, n is an even)

If x = 4cosA + 5sinA and y = 4 sinA - 5 cosA, then the value of x^2+y^2 is : यदि x = 4cosA + 5sinA तथा y = 4 sinA - 5 cosA है, तो x^2+y^2 का मान क्या होगा ?

If cotA=(4)/(5) , then ((sinA+cosA))/((sinA-cosA))=?
