Question

tan A - sin A = 1/12

Answer 1

We can plot this equation and solve it graphically:

We will have next solution:

$x\approx 2.(3.14159n - 1.54997),\quad n\in \mathbb{Z}$

$x\approx 2.(3.14159n + 0.268029),\quad n\in \mathbb{Z}$

$x\approx 2.3.14159n - (0.14443 + 0.238498i),\quad n\in \mathbb{Z}$

$x\approx 2.3.14159n - (0.14443 - 0.238498i),\quad n\in \mathbb{Z}$

Answer:

$x\approx 2.(3.14159n - 1.54997),\quad n\in \mathbb{Z}$

$x\approx 2.(3.14159n + 0.268029),\quad n\in \mathbb{Z}$

$x\approx 2.3.14159n - (0.14443 + 0.238498i),\quad n\in \mathbb{Z}$

$x\approx 2.3.14159n - (0.14443 - 0.238498i),\quad n\in \mathbb{Z}$
