Question

show that the equation sin theta + cos theta =2(sin theta -cos theta) can be expressed as tan theta = 3​

Answer 1

Explicação passo-a-passo:

sin(a)+cos(a)=2sin(a)-2cos(a).

3cos(a)=sin(a).

tan(a)=sin(a)/cos(a)

sin(a)/cos(a)=3

sin(a)=3cos(a)

Seeing that the equations can be simplified to be the same, they are equal
