`(1+Cosθ)^2/sin^2θ = (1+cosθ)/(1-cosθ)`

If (sinθ/(1+ cosθ)) + ((1 +cosθ)/sinθ) = 4/sqrt3 0^circ lt θ lt 90^circ , then the value of (tanθ + secθ)^(-1) is : यदि (sinθ/(1+ cosθ)) + ((1 +cosθ)/sinθ) = 4/sqrt3 0^circ lt θ lt 90^circ ,, तो (tanθ + secθ)^(-1) का मान है :

The value of ((sinθ -cosθ )(1 + tanθ + cotθ ))/(1+sinθ cosθ ) = ? ((sinθ -cosθ )(1 + tanθ + cotθ ))/(1+sinθ cosθ ) का मान है :

Prove the following trigonometric identities: sinθ/(1+cosθ) + (1+cosθ)/sinθ = 2/sinθ

If sqrt((1-cosθ)/(1+cosθ)) xx sqrt((cosecθ -cot θ)/(cosecθ +cot θ))= (1-r)/(1+r) , then the value of r is: यदि sqrt((1-cosθ)/(1+cosθ)) xx sqrt((cosecθ -cot θ)/(cosecθ +cot θ))= (1-r)/(1+r) है तो r का मानहैः

(sinθ - 2sin^3θ)/(2cos^3θ - cosθ) = tanθ

The value of ( 1 + cotθ – cosecθ ) ( 1 + cosθ + sinθ )secθ = ? ( 1 + cotθ – cosecθ ) ( 1 + cosθ + sinθ )secθ का मान है :
