ನಿರ್ಣಾಯಕ `[{:(,0,1,sec alpha),(,tan alpha) ನಲ್ಲಿ ಮೂರು-ಒಂದು ಅಂಶ `(ieM_(31))` ಚಿಕ್ಕದಾಗಿದ್ದರೆ

1+tan alpha*tan((alpha)/(2))

If sec alpha,tan alpha are roots of ax^(2)+bx+c=0 then

If minor of three-one element (i.e.M_(31)) in the determinant [{:(,0,1,sec alpha),(,tan alpha,-sec alpha,tan alpha),(,1,0,1)]:} is 1 then find the value of alpha (0 le alpha le pi).

(sec8 alpha-1)/(sec4 alpha-1)=(tan8 alpha)/(tan2 alpha)

If 0

If sec alpha=(5)/(4), evaluate (1-tan alpha)/(1+tan alpha)

If sec alpha = (5)/(4) then (tan alpha )/( 1 + tan ^(2) alpha ) is equal to

if (1+tan alpha)(1+tan4 alpha)=2 where alpha in(0,(pi)/(16)) then alpha equal to

sec^(4)alpha(1-sin^(4)alpha)-2tan^(2)alpha=?
