If `tanx+tany=25` and `cotx+coty=30` then

If tanx+tany=(5)/(6) and cotx+coty=5 , then tan(x+y) is

In the following questions, write 'T' for truee and 'F' for false statements. If tanx + tany = 5 and tanx. tany =1/2 then cot(x+y) = 10

x-y = pi/4 and cotx + coty=2

If tan x - tany =a " and " coty - cotx =b, "prove that", 1/a +1/b = cot (x-y).

tanx + cotx=2

If tanx tany=a and x+y=2b show that tanx and tany are the roots of the equation z^2-(1-a)tan2b*z+a=0

If tanx tany=a and x+y=2b show that tanx and tany are the roots of the equation z^2-(1-a)tan2b*z+a=0

If 1-tanx/1+tanx=tany and x-y=pi/6 , then x, y are respectively

If cosx=tany ,coty=tanz ,cotz=tanx , then the value of sinx is (a) 2cos18^0 (b) cos18^0 (c) sin18^0 (d) 2sin18^0
