- Homework Statement
- Show that ##2 \cos \theta +(1- \tan \theta)^2≈ 3 - 2\theta##
- Relevant Equations
- trigonometry
This is a past paper question...
find the solution here from ms
...wawawawawa...it took a little bit of my time because i was only thinking of taking limits...then realized that i was wrong as we have to remain with ##2θ##...i later realized that for small approximations, ##\cos θ≈1-\frac {1}{2}θ^2, \tan θ≈θ##.
Is there a different way of solving this problem?
