tan alpha=(5)/(12)

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

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

If tan alpha = (5)/(6) tan beta = (1)/(11) then the value of alpha + beta is

If sin alpha=(15)/(17) and cos beta=(12)/(13) find the values of sin(alpha+beta),cos(alpha-beta) and tan(alpha+beta)

Find the value of sin (alpha - beta), cos (alpha -beta) and tan (alpha - beta), given sin alpha = (8)/(17) , tan beta = (5)/(12), alpha and beta in Quadrant I.

If alpha,beta are acute angles, sin alpha = (4)/(5), tan beta = (5)/(12) then the descending order of A= sin (alpha+beta), B cos(alpha+beta),C= tan(alpha+beta) is

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

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

If alpha=tan^(-1)(t a n(5pi)/4)a n dbeta=tan^(-1)(-tan(2pi)/3),t h e n 4alpha=3beta (b) 3alpha=4beta (c) alpha-beta=74alpha=(3beta)/(12) none of these

If alpha=tan^(-1)(t a n(5pi)/4)a n dbeta=tan^(-1)(-tan((2pi)/3)),t h e n (a) 4alpha=3beta (b) 3alpha=4beta (c) alpha-beta=74alpha=(3beta)/(12) (d) none of these
