If sec alpha = (13)/(5) " where " alpha lt 90^(@) , then the value of (2-3 cot alpha )/(4-9 tan alpha ) =

If sec alpha=(5)/(4), verify that (tan alpha)/(1+tan^(2)alpha)=(sin alpha)/(sec alpha)

" If cos(alpha+beta)=(3)/(5) sin(alpha-beta)=(5)/(13) and 0< alpha, beta < (pi)/(4) then tan(2 alpha) is equal to

If cos (alpha+beta)=(4)/(5), sin (alpha-beta)=(5)/(13) and 0 lt alpha , beta lt(pi)/(4), then tan 2 alpha=

If cos (alpha+beta)=(4)/(5), sin (alpha-beta)=(5)/(13) and 0 lt alpha, beta lt (pi)/(2) then cos 2 alpha=

If sin alpha=(12)/(13), cos beta =4/5 and alpha, beta are two acute angles, then Value of sec alpha cot beta +tanalpha cosec beta is
