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

If tan alpha = (5)/(12) ,find the value of sec alpha .

If tan alpha=2 , then the value of (cosec^2 alpha-sec^2 alpha)/(cosec^2 alpha+sec^2 alpha) is यदि tan alpha=2 है, तो (cosec^2 alpha-sec^2 alpha)/(cosec^2 alpha+sec^2 alpha) का मान ज्ञात करें।

If sin(alpha+beta)=(4)/(5), sin(alpha-beta)=(5)/(13) , find the value of tan 2alpha :

tan(alpha+beta)=(1)/(2),tan(alpha-beta)=(1)/(3), then find the value of tan2 alpha

If sec^(2)alpha+cos^(2)alpha=2 , then find the value of sec alpha+ cos alpha .

If cos alpha=(3)/(5), then value of (sin alpha-(1)/(tan alpha))/(2tan alpha) is

If tan alpha = sqrt3+2 , then the value of tan alpha - cot alpha is

If sec alpha=(2)/(sqrt3), the find the value of (1-"cosec "alpha)/(1+"cosec "alpha) , where alpha is in IV quadrant.

" If alpha=(2 pi)/(7) ,then the value of tan alpha tan2 alpha+tan2 alpha tan4 alpha+tan4 alpha tan alpha is "
