Question

y=sin2x
how do you calculate the x-intercepts?

Answer 1

its not a st. line so no question about this.
it has infinite no of solution when y=0
sin2x=0
x=npi/2

Answer 2

ok, what are the x-intercepts in the domain of 0-2pi

Answer 3

then it is 0,pi/2, pi,3pi/2, 2pi

Answer 4

if the domain is (0,2pi) instead of [0,2pi] then u have to exclude the terms 0 and 2pi

Answer 5

i think u are enough intelligent to understand this.

Answer 6

alright yeah, i get it now cheers

Answer 7

good...cheers.
