`sinθ/(1-cosθ) = (1+cosθ)/sinθ`

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

(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 :

x = a(θ - sinθ), y = a(1 + cosθ) Find dy/dx

If ((sinθ−cosecθ)(cosθ−secθ))/(tan^(2)θ -sin^(2)θ) = r^3 , then r=? यदि ((sinθ−cosecθ)(cosθ−secθ))/(tan^(2)θ -sin^(2)θ) = r^3 है तो r बराबर हैः

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
