haha dont worry my MX1 test was on the last day of school and my MX2 test was on in the holidays, I had to come back two days after school finished lol
ok another question lol.....i equated the real and imaginary parts and im trying to figure out wat tan4@ equals. This is wat i hav im not sure if its right:
tan4@=sin4@/cos4@
tan4@=4isin@cos^3@-4icos@sin^3@/8cos^4@-8cos^2@
tan4@=......dunno where to go lol
thnx heaps guys
yea i got to that line: cos^4@ - 6sin^2@cos^2@ + 4isin@cos^3@ - 4icos@sin^3@ + sin^4@......but didnt know where to go after that. Thnx heaps for the help
I hav a question for homework which i just cant seem to figure out
It says Express:
(a) cos4θ in terms of cosθ
(b) sin4θ in terms of cosθ and sinθ
(c) tan4θ in terms of tanθ
