Asked by Monika
What would be the 2 solutions to this equation?
sinx(tanx) + tanx = sqrt(3)(sinx) + sqrt(3)
I know that "x = pi/3 +pi k" is one, but I need help finding the other.
Cheers

sinx tanx + tanx = √3 sinx + √3
tanx(sinx+1) = √3 (sinx+1)
(tanx-√3)(sinx+1) = 0
tanx = √3
sinx = -1
That help?
tanx(sinx+1) = √3 (sinx+1)
(tanx-√3)(sinx+1) = 0
tanx = √3
sinx = -1
