slvri:
zeroes of g? never heard of the zeroes of a function b4 :-\

astarmathsandphysics:
Same as the roots

astarmathsandphysics:
When i get home

astarmathsandphysics:

let g(x) = log5|2log3x|=0
2 log3x=1 so x=sqrt(3)
Have I got the question right? I can only see one root.

IGSTUDENT:
Posting my queries:

1.prove that cos^6(x)+ sin^6(x)=1/8(3cos4x+5)

2.Prove that tan5x=(5tanx-10tan^3(x)+tan^5)/(1-10tan^2(x)+5tan^4(x)). By considering the equation tan5x=0, show that tan^2(pi/5)=5-2sqrt5.

For the 2nd question I was able to do the first part but not the second

Thanks
