Solve the trigonometric equation for the domain is. 0°<x<360°

5(sinx - cosx) = 4sinx - 3cosx

2) Relevent equations:

secx=1/cosx

cosec x=1/sinx

cot x= 1/tanx

tan x=sinx/cosx

cot x=cosx/sinx

sin^2 x + cos^2 x=1

1 + tan^2 x= sec^2 x

1+ cot^2 x = cosec^2 x

Template of answer:

New domain:

Basic angle=

Quadrants=

Solve for x

3)Attempt the question

5(sin x - cosx)=4sinx - 3cosx

5sinx-4sinx-5cosx+3cosx=0

sinx - 2 cos x=0
