it says to verify the following identity, working only on one side: cotx+tanx=cscx*secx Work the left side. cot x + tan x = cos x/sin x + sin x/cos x = (cos^2 x +sin^2x)/(sin x cos x) = 1/(sin x cos x) = 1/sin x * 1/cos x You're

Prove the identity sin(x+y+z)+sin(x+yz)+sin(xy+z)+ sin(xyz) = 4 sin(x)cos(y)cos(z) This identity is so long and after i tried to expand the left side and it just looked something crap Thanks for you help :)

I need to prove that the following is true. Thanks. csc^2(A/2)=2secA/secA1 Right Side=(2/cosA)/(1/cosA  1) = (2/cosA)/[(1cosA)/cosA] =2/cosA x (cosA)/(1cosA) =2/(1cosA) now recall cos 2X = cos^2 X  sin^2 X and we could say

Prove each identity: a) 1cos^2x=tan^2xcos^2x b) cos^2x + 2sin^2x1 = sin^2x I also tried a question on my own: tan^2x = (1 – cos^2x)/cos^2x R.S.= sin^2x/cos^2x I know that the Pythagorean for that is sin^2x + cos^2x That's all

Find sin(x/2) if sin(x)= 0.4 and 3pi/2 < or equal to (x) < or equal to 2pi Let's use cos 2A = 1  2sin2 A and we can match cos x = 1  2sin2 (x/2) so we will need cos x we know sin x = .4 and x is in the fourth quadrant, so the

Where do I start to prove this identity: sinx/cosx= 1cos2x/sin2x please help!! Hint: Fractions are evil. Get rid of them. Well, cos2x = cos2x  sin2x, so 1coscx = 1  cos2x  sin2x = 1  cos2x + sin2x You should be able to
