tanx-sinx=0.75
How You Solve Sin X = Tan X?
tgx-sinx=0.75
Tanx=sinx
sinx/cosx=sinx
sinx=sinx*cosx
0=sinx*cosx-sinx
0=sinx(cosx-1)
sinx=0 cosx=1
x1=k*pi x2=2*k*pi ; k € IR
x1 covers both so x=k*pi.
sinx/cosx=sinx
sinx=sinx*cosx
0=sinx*cosx-sinx
0=sinx(cosx-1)
sinx=0 cosx=1
x1=k*pi x2=2*k*pi ; k € IR
x1 covers both so x=k*pi.
Since tanx = sinx/cosx,
sinx = sinx/cosx
multiply both sides by cosx
so sinxcosx = sinx
divide both sides by sinx
cosx = 1
x = 2pi
does that sound right? I'm doing an assignment with this question right now :)
