" If "sec alpha=13/5(0

If sec alpha=(13)/(5) where 270^(@)ltalphalt360^(@) then what is sin alpha equal to ?

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 sin alpha=(5)/(13) , then show that tan alpha + sec alpha=1.5 .

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

" 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)=3/5 , sin(alpha-beta)=5/13 and 0

If "tan" alpha=(5)/(2) , find the value of sec alpha .

Solve : tan ^(2) alpha + sec alpha - 1 = 0,0 le alpha lt 2pi.

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