`(1-sinθ)(1+sinθ)(1+tan^(2)θ)` = 1

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

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

√(1+sin θ) ( 1 - sin θ) is equal to

Prove that : tan^(-1) 1 + tan^(-1) 2 + tan^(-1) 3= pi = 2(tan^(-1) 1 + tan^(-1)((1)/(2)) + tan^(-1)( (1)/(3)))

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 :

If 2cos^(2)θ + 3sinθ = 3 , where 0^circ lt θ lt 90^circ , then what is the value of sin^(2)2θ + cos^2 (θ) + tan^(2)2θ + cos^(2) 2θ = ? यदि 2cos^(2)θ + 3sinθ = 3 , जहा 0^circ lt θ lt 90^circ तो sin^(2)2θ + cos^(2(θ + tan^(2)2θ + cos^(2)2θ का मान बराबर है :

If θ lies in the first quadrant and cos^(2) θ – sin^(2) θ = 1/2 , then the value of tan^(2)2θ + sin^(2)3θ is: यदि θ प्रथम चतुथथांश में है और cos^(2) θ – sin^(2) θ = 1/2 , तो tan^(2)2θ + sin^(2)3θ का मान है:

If (1+tan1^(@)) *(1+tan2^(@))*(1+tan3^(@)) …….(1+tan45^(@)) = 2^(n) , then 'n' is equal to :
