`sin^2 A+cos^2 A+tan^2 A=`

If sinA=3/5 , where 0^(@)ltA lt 90^(@) , find the values of sin 2A, cos 2A, tan 2A and sin 4A .

Prove :sin^(2)A cot^(2)A+cos^(2)A tan^(2)A=1

Evaluate sin2A, cos2A and tan2A if: i) sinA=5/13 , ii) cosA=8/17 , iii) tanA=4/3

Find the value of sin^2 30^@+cos^2 60^@+tan^2 45^@ .

sin ^ (2) A.cot ^ (2) A-cos ^ (2) A * tan ^ (2) A = 1

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 :

The numerical value of ( cos^2 45^@ ) /( sin ^2 60 ^@) +( cos ^2 60^@ )/( sin ^2 45 ^@ ) -(tan ^2 30 ^@ )/( cot^2 45^@ ) -( sin^2 30 ^@ )/( cot^2 30^@) is

(sin A + sin2A) / (1 + cos A + cos2A) = tan A

If sin A=(3)/(5) and 0^(@)
