Question

Find the exact solutions to each equation for the interval 0 13 years ago

Answer 1

Divide each side by sin x

Answer 2

so its cos x=0?

Answer 3

no
cosx=1

Answer 4

which means that x=0 or 2*pi
right?

Answer 5

wow.... 0<x<2pi... no =
if that is the case => no solution

Answer 6

the problem states that x is greater than or equal to 0. so i would assume its 0. i just couldnt add in the equal to symbol

Answer 7

next time type: >= or <=
everybody will understand :)
if <= then 2 solutions:
0 and 2pi

Answer 8

okay thanks for the tip and answer

Answer 9

welcome!

Answer 10

sinxcosx=sinx
sinxcosx-sinx=0
sinx(cosx-1)=0
sinx=0 cosx-1=0
sinx=0 cosx=1
x=0 x=0
x=pi x=2pi
x=2pi

Answer 11

you guys missed a solution

Answer 12

isnt it just 0 and 2pi?

Answer 13

and pi

Answer 14

oh, alright thanks, would have missed that
