" 7.If "sin alpha=(3)/(5)" tan "beta=(1)/(2)" and "(pi)/(2)

If sin alpha=(3)/(5),tan beta=(1)/(2) and (pi)/(2)

If cos alpha=-(3)/(5) and sin beta=(7)/(25) where (pi)/(2)

If sin alpha = 3/5, tan beta = 1/2 and pi/2 lt alpha lt pi lt beta lt (3pi)/2 , show that 8 tan alpha - sqrt(5) sec beta = - 7/2 .

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

cos (alpha+beta)=(3)/(5) and sin (alpha-beta)=(3)/(5) and 0 lt alpha, beta lt (pi)/(2) then sin 2 alpha=

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

Find the values of tan (alpha + beta) , given that cot alpha = (1)/(2) alpha in (pi, (3pi)/(2)) and sec beta = - (5)/(3), beta in ((pi)/(2),pi) .

If cot alpha=1/2, alpha in (pi,(3pi)/2) and sec beta=(-5)/3, beta in ((pi)/2, pi) find tan (alpha+beta)
