Question

If (m+2)sin ø + (2m-1)cos ø = 2m+1 then tan ø is equal to (2m) /(m^2-1)

Answer 1

Answer:

using x to avoid copy/paste of ø,

m sinx + 2sinx + 2m cosx - cos x = 2m+1

(sinx + 2cosx)m + (2sinx - cosx) = 2m+1

If these are identical, then

sinx + 2cosx = 2

2sinx - cosx = 1

sinx = 4/5

cosx = 3/5

tanx = 4/3
