Alpha:
3x= 4 sin x.

You can draw y = 3x and y= 4 sin x.

In case don't find any other way, you can try it.


Sign change method...?

astarmathsandphysics:
x            3x-sinx
1      -0.37
1.05      -0.32
1.1      -0.26
1.15      -0.2
1.2      -0.13
1.25      -0.05
1.3      0.05
1.35      0.15
1.4      0.26
1.45      0.38
1.5      0.51
1.55      0.65
sign change between x=1.2 and 1,43 rads x=1.25 is too small sox=1.3 to 1 dp

Thanks :)

but could you also show it the other way(tabulation)...it would help me in the future

astarmathsandphysics:
