Prove `sinA/(1+cosA)+(1+cosA)/sinA=2cosecA`

cosA/(1−sinA) =

Prove that: (sinA)/(1+cotA) -(cosA)/(1+tanA)=sinA-cosA

Prove that 4sinA.cosA.cos2A=sin4A

Solve sinA.cos(A-B)-cosA.sin(A-B)

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.

Prove that (1+sin2A)/(cos2A)=(cosA+sinA)/(cosA-sinA)=tan((pi)/(4)+A)

Prove that: sinA(1+tanA)+cosA(1+cotA)= secA+"cosec"A

Prove: (sinA)/(secA+tanA-1)+(cosA)/(cos e c\ A+cotA-1)=1

Prove: (1+cosA)/(sinA)=(sinA)/(1-cosA)

sinA/( 1+cosA) +sinA/(1−cosA) is equal to
