सिद्ध कीजिए कि `sin^(2)((pi)/(8)+(A)/(2))-sin^(2)((pi)/(8)-(A)/(2))=(1)/(sqrt2)sinA`

सिद्ध कीजिए कि sin^(2)((pi)/(8)+(A)/(2))-sin^(2)((pi)/(8)-(A)/(2))=(1)...
Text Solution
|
sin^2(A/2+pi/8) - sin^2(A/2-pi/8)= 1/sqrt(2)sinA
Text Solution
|
Prove that: sin^2(pi/8+A/2)-sin^2(pi/8-A/2)=1/sqrt(2)sinA
Text Solution
|
sin^2(pi/8+A/2)-sin^2(pi/8-A/2)=1/(sqrt(2))sinA
Text Solution
|
