Question

solve the equasion : sinx/cosx = 0

Answer 1

when sin(x) = -cos(x)

which is in the second and fourth quadrants at a 45deg angle or

deg 135 or 315.

Answer 2

sinx/cosx can rewriten as tanx
so, tanx = 0
what angles make the tan be 0 ?
these is special angles in trigonometry

Answer 3

thank you

Answer 4

you're welcome, i sure u got it :)

Answer 5

yes i understood it.but hey,what about the equasion : sinx/x = 0

Answer 6

sinx/x ?

Answer 7

well yes.sinx devided by x = 0 and we have to solve the equasion

Answer 8

i think we can cross multiplied, because it is equation = 0
so, sinx/x = 0
sinx = x * 0
sinx = 0
solve for x

Answer 9

uhm,okk,thanks again

Answer 10

welcome again :D
