Question

Solve . sin(^2)x-3sinxcosx+2cos(^2)x=0

Answer 1

try factoring

Answer 2

(Sin(x) - Cos(x) ) (Sin(x) - 2 Cos(x))=0

Answer 3

Sin(x) - Cos(x) =0

Sin(x)= Cos(x)

that's true when x is Pi/4 + Pi n (n=1,2,3,4)

Answer 4

(Sin(x) - 2 Cos(x))=0


Sin(x)=2 Cos(x)

tan(x)=2

arctan(2)

Answer 5
