verify that: cos^3(x)+sin^3(x)=1/2* (cos(x)+sin(x))*(2-sin(2x))
verify that: cos^3(x)+sin^3(x)=1/2* (cos(x)+sin(x))*(2-sin(2x))
Show that if α, β and γ are the angles of a triangle, then we would have but tanα+tanβ+tanγ=tanαtanβtanγ I need help with this. I've been trying but getting nowhere. Thanks....
I thought it could possible be solved by a double angle formula, but I cant seem to make it work
find all the solutions of the given equation in the interval 0≤x<2pi
Having trouble with these two problems... Verify each identity sin2 x/2=csc x-cot x/2 csc x 2tan x/2=sin2 x +1 - cos2 x/sin x (1+ cos x)
Use a graphing calculator to approximate, to three decimal places, the solutions to the equation. If there is more than one solution write them separated by comas.
(tanv+1)^2(tanv-1)^2=2sec^2v
This is for my trig class. Thanks for the help!
A. sin22.5 degrees and B. tanpi/12 degrees
I am trying to find an equation to satisfy these conditions. I have tried 5900(.96t) and that is not the correct answer. I am in a trigonometry class so I think that it might have to include sine...
