A = 5^(@) ಆಗ ಅಭಿವ್ಯಕ್ತಿಯ ಮೌಲ್ಯ ((secA)/((1 - 4sin^(2)A)) + (cosec A)/((4 cos^(2)A -1).. .

If A = 5^(@) then the value of expression (( secA)/((1 - 4sin^(2)A)) + (cosec A)/((4 cos^(2)A -1)))^(2) is :

(1+secA)/secA=(sin^2A)/(1-cosA)

(cot^(2)A*sec A)/(cos^(2)A*sin^(2)A)=sec A*cosec^(4)A

int(1)/(4sin^(2)x+4sin x cos x+5cos^(2)x)dx

"cosec"(sin^(-1)x+cos^(-1)x)

if sin A=(1)/(4) then cosec^(-1)4

2sin ^ (2) A + cos ^ (4) A-1 + sin ^ (4) 4

Prove that (1+secA)/(secA)=(sin^(2)A)/(1-cosA).

sin [(1) / (2) (cos ^ (- 1) 4) / (5)]
