Question

y=1-(sin3x-cos3x)^2 equals with y=sin6x
(X belongs to R)....but how do u get it? O.o May some1 pls help me?

Answer 1

essentially both are the same equation.

Answer 2

open the squared term and u'll end up getting 2sin3xcos3x=sin6x

Answer 3

yea i know tht...but how do u transform the 1st into the second?

Answer 4

really?

Answer 5

ok,wait

Answer 6

I got it!!! Yuupiiii!! :) Thnx :)

Answer 7

1-(sin3x-cos3x)^2=1-(sin^2(3x)+cos^2(3x)-2sin3xcos3x)=1-1+2sin3xcos3x=sin6x . fine ?

Answer 8

Yea thnx :)
